How does one successfully download AND import pygame?

the problem:
as part of my studies, i have tried to download PyGame for my own independent project. I've currently downloaded 1.9.6, as well as currently owning IDLE version 3.8. i have imported it many times:
folder.
on one occasion , i placed it in its own separate folder with the coding file in another internal folder
when importing it into a new python script, the result was that there was "no module named Pygame", even though it was in a file containing the recent edition (this method was used successfully to download Tkinter).
I also tried making a python script outside the contained folder like this
this,too had the same result.
Any idea what exactly to do?
any more important information
The computer type is a MAC 10.13.6 and the IDE is IDLE. As previously mentioned, the downloaded version is version 1.9.6 and i have not a clue what how many bits my computer manages. Apologies that this is probably one of MILLIONS of the exact same question answered.I've tried at least 2 of these solutions.

First you need to make sure that you have pip installed. Type pip in your cmd (command prompt) and if you get no errors you are fine. If you have errors follow this link to get it. If you are stuck on that link - basically all you need to do is uninstall python and then when you are installing it again tick the box that says:
Add Python 3.5 to PATH
Now just finish installing python.
Next you need to install pygame with pip install pygame in your cmd - run it as administrator just to be safe. If you receive errors try updating pip with python -m pip install --upgrade pip. Now create and save a new python file. Import pygame in that file by using the code import pygame. The output should be:
pygame 1.9.6
Hello from the pygame community. https://www.pygame.org/contribute.html
Now you are free to code in pygame! I hope this helped.

How to install a module on Python?

Okay, so, I'm actually a beginner in programming Python, and I only found out yesterday how you were supposed to encode pip install ModuleName in the Python command line and not in the interactive shell. I'm trying to download a lot of modules, such as the Send2Trash module, Pyperclip, Requests, Beautiful Soup, and Selenium.
Before I checked the forums about installing modules, I found out how we needed to have the pip tool. I'm a Windows user, but for some reason, I didn't have the 'Scripts' folder installed when I downloaded Python. I didn't know we needed it, so I used raw scripts from GitHub, setup.py, and copy pasted the script into the File Editor in Python, ran it in the interactive shell, and tried to import the module I needed. It worked for the Pyperclip and the Requests module; no errors popped up after I imported them using import pyperclip or import requests, but when I tried the same procedure for the rest of the modules I needed, there were some errors.
Also, when I tried to download the modules on pypi.python.org, I tried to open it using the interactive shell, but then something pops up, 'The file's encoding is invalid for Python3.x...', and when I click 'OK', it's going to say 'Failed to Decode', and close everything.
So, after reading forum after forum, I found out how to download pip, and was also able to download setuptools and wheel. I'm not sure if it's really already downloaded, but I was able to get the 'Scripts' folder that wasn't there before, so I guess so. I also already went into my PATH using the edit environment for your account thing, and I edited the Path variable so its value would lead to my 'Scripts' folder. Please do tell me if I did the right thing here.
So, following the advice of the forums, I tried to install the modules I needed by typing pip install ModuleName in the Python command line instead of the interactive shell, but it still gave me a Syntax Error. I also tried it in Command Prompt, typing the same code pip install ModuleName, but when I clicked Enter, nothing happens; no errors or anything. It seemed like my install was accepted, but when I tried importing the module in the interactive shell, it still gave an Import Error.
Please tell me what I did wrong throughout my process, and how to properly install the modules I need. I would include pictures into this, but it seems I can only add two before my reputation becomes 10, and I'm pretty new here, so... If there's anything I need to elaborate on about my problem, don't hesitate to ask, and I'll try my best.

You say you use windows so you need to understand pip.
pip is a program that installs python modules. You can even use easy_install instead of pip.
some pip commands
pip list -- lists out already installed modules.
pip search <module name> -- searches new modules.
pip -h -- more pip commands you want.
pip installs modules from CMD prompt not from python shell.
Even after installing modules some modules doesn't run as import module
they need to be imported as from module import function.
refer the pip help command and install modules.
DO NOT SAVE SCRIPT FILES IN PYTHON ROOT FOLDER YOU MAY FACE SOME PROBLEMS
Happy Programming!!!

After a whole lot of searching and trying out, I found the solution to my problem. For future Python users who encounter the same thing: always install your modules in the root folder.
In my case, my Command Prompt was automatically inside the C:\Users folder, which caused some problems because I couldn't download my module in there. Once I typed in cd C:\Python34, which was my root folder, I could successfully download the modules I needed using pip install ModuleName.

How to import win32api module in python? [duplicate]

When running python26 under windows OS (64bits).....
I have got errors like:
import win32api" error in Python 2.6: pywintypes26.dll
or
pythoncom26.dll missing
ImportError: DLL load failed: The specified module could not be found.
I have done the msi installation for python26
all dlls can be found under C:\Python26\Lib\site-packages\pywin32_system32

After I copy pywintypes26.dll and pythoncom26.dll from C:\Python26\Lib\site-packages\pywin32_system32 to C:\Python26\Lib\site-packages\win32 -> Solve the problem!

I also hit a problem importing win32api.
The post-install script for pywin32 failed, which should copy pythoncom26.dll, pythoncomloader26.dll, and pywintypes26.dll, among other things. I ran it by hand and my installation was fixed.
python scripts\pywin32_postinstall.py -install

I had a similar problem when installing under 64 bit Python 3.4.2. I ran the install executable pywin32‑219.win‑amd64‑py3.4.exe from http://www.lfd.uci.edu/~gohlke/pythonlibs/ .
On the site it states clearly:
"Python 3.4 users must manually run python.exe Scripts\pywin32_postinstall.py -install from an elevated command prompt."
which I did not do first time round; I installed from a normal prompt getting the following feedback:
c:\python34>python.exe Scripts\pywin32_postinstall.py -install
Copied pythoncom34.dll to C:\Python34\pythoncom34.dll
Copied pywintypes34.dll to C:\Python34\pywintypes34.dll
You do not have the permissions to install COM objects.
The sample COM objects were not registered.
etc.etc.
Finishing with "The pywin32 extensions were succesfully installed" ...
I only read the last sentence and I started to run some code resulting in getting these dll load fails.
So, did some research, and started an elevated prompt (how: see "http://www.sevenforums.com/tutorials/783-elevated-command-prompt.html") and again ran:
c:\python34>python.exe Scripts\pywin32_postinstall.py -install
Copied pythoncom34.dll to C:\Windows\system32\pythoncom34.dll
Copied pywintypes34.dll to C:\Windows\system32\pywintypes34.dll

Pythonwin has been registered in context menu
Shortcut for Pythonwin created
Shortcut to documentation created
The pywin32 extensions were successfully installed.
And now my code runs happily (as far as this matter is concerned... sigh, so much other stuff to do).

Run the installer as Administrator and it works:
Right click on pywin32-installer.exe
Choose "Run as Administrator"

As suggested above the post install script is not run, this issue can be seen when installing from a wheel (As I encountered)
python scripts\pywin32_postinstall.py -install
If find you have this issue when installing via wheels, then installing it from here can solve the above issue.
https://pypi.python.org/pypi/pypiwin32

There appears to be a bug in the installer. The recommended workaround in the ticket is the same one as proposed by Dave Bremer.

I could fix this situation by removing all installed Python3.4 versions (had forgotten to uninstall 3.4.1 before installing 3.4.2), deleting C:\Python34 and after installing Python 3.4.2 pywin32-219.win32-py34.exe could be installed and called without problems.
So, copying around DLLs should NOT be necessary!

I always install the Active State Python distro which installs the win32 packages for you and gets it right.

If the above didn't fix the problem, you're still missing the msvcr100.dll file. It's either in your \System32\ folder, or more likely in your c:\PythonXX\Lib\site-packages\win32\ folder.
That fixed it for me after hours of search to no avail, even though it looks like the import still isn't resolved as it should be (PyCharm still gives me the squiggly underline), but it works.

First I was using pip to install pywin32 in anaconda environment, that's why no matter what I did it was failing. After trial and error, I figured out that
conda install pywin32
is the right way to install pywin32 in the anaconda package manager.

I don't know whether it's too late or not to answer this question. I also hit this problem, and I tried every method above, but neither of them worked.
Finally, I found the reason. When we install pywin32, we must choose the one that fits python's version(2.6， 2.7， 3.3， etc) and python's bit number(x64 or x86). Notice, it must fit python's bit number, not PC's bit number. If you install x86 python in a x64 PC, you have to install a pywin32 with x86.

In my case i had to copy pywintypes26.dll and pythoncom26.dll files into C:\Windows\System32 folder to work it properly in jupyter notebook.

Installing OpenCV - DLL load failed: %1 is not a valid Win32 application [duplicate]

I have a situation very much like the one at Error "ImportError: DLL load failed: %1 is not a valid Win32 application", but the answer there isn't working for me.
My Python code says:
import cv2
But that line throws the error shown in the title of this question.
I have OpenCV installed in C:\lib\opencv on this 64-bit machine. I'm using 64-bit Python.
My PYTHONPATH variable: PYTHONPATH=C:\lib\opencv\build\python\2.7. This folder contains cv2.pyd and that's all.
My PATH variable: Path=%OPENCV_DIR%\bin;... This folder contains 39 DLL files such as opencv_core246d.dll.
OPENCV_DIR has this value: OPENCV_DIR=C:\lib\opencv\build\x64\vc11.
The solution at Error "ImportError: DLL load failed: %1 is not a valid Win32 application" says to add "the new opencv binaries path (C:\opencv\build\bin\Release) to the Windows PATH environment variable". But as shown above, I already have the OpenCV binaries folder (C:\lib\opencv\build\x64\vc11\bin) in my PATH. And my OpenCV installation doesn't have any Release folders (except for an empty one under build/java).
What's going wrong? Can I tell Python to verbosely trace the loading process? Exactly what DLL files is it looking for?
I noticed that, according to http://www.dependencywalker.com/, the cv2.pyd in C:\lib\opencv\build\python\2.7 is 32-bit, whereas the machine and the Python I'm running are 64-bit. Could that be the problem? And if so, where can I find a 64-bit version of cv2.pyd?

Unofficial Windows Binaries for Python Extension Packages
You can find any Python libraries from here.

Please check if the Python version you are using is also 64 bit. If not then that could be the issue. You would be using a 32-bit Python version and would have installed a 64 bit binaries for the OpenCV library.

Wow, I found yet another case for this problem. None of the above worked. Eventually I used python's ability to introspect what was being loaded. For Python 2.7, this means:
import imp
imp.find_module("cv2")
This turned up a completely unexpected "cv2.pyd" file in an Anaconda DLL directory that wasn't touched by multiple uninstall/install attempts. Python was looking there first and not finding my good installation. I deleted that cv2.pyd file and tried imp.find_module("cv2") again and python immediately found the right file and cv2 started working.
So if none of the other solutions work for you, make sure you use Python introspection to see what file Python is trying to load.

In my case, I have 64-bit Python, and it was lxml that was the wrong version--I should have been using the x64 version of that as well. I solved this by downloading the 64-bit version of lxml here:
https://pypi.python.org/pypi/lxml/3.4.1
lxml-3.4.1.win-amd64-py2.7.exe
This was the simplest answer to a frustrating issue.

I just had this problem. It turns out it was just because I was using an 64-bit version of the OpenCV file. I tried the x86 and it worked.

I had the same problem. Here's what I did:
I downloaded the pywin32 wheel file from here, then
I uninstalled the pywin32 module. To uninstall, execute the following command in a command prompt.
pip uninstall pywin32
Then, I reinstalled pywin32. To install it, open the command prompt in the same directory where the pywin32 wheel file lies. Then execute the following command.
pip install <Name of the wheel file with extension>
Wheel file will be like: piwin32-XXX-cpXX-none-win32.whl
It solves the problem for me.

I copied cv2.pyd file from /opencv/build/python/2.7/x86 folder instead of from /x64 folder to C:/Python27/Lib/site-packeges. I followed rest of the instructions provided here.
Added by someone else, not verified: I also copy file cv2.pyd to folder C:/Python27/Lib/site-packages/cv2. It works.

For me the problem was that I was using different versions of Python in the same Eclipse project. My setup was not consistent with the Project Properties and the Run Configuration Python versions.
In menu Project → Properties → PyDev, I had the Interpreter set to Python 2.7.11.
In Run Configurations → Interpreter, I was using the Default Interpreter. Changing it to Python 2.7.11 fixed the problem.

If your build system (CMake in my case) copies the file from <name>.dll to <name>.pyd, you will get this error if the original file wasn't actually a DLL file. In my case, building shared libraries got switched off, so the underlying file was actually a *.lib.
I discovered this error by loading the pyd file in Dependency Walker and finding that it wasn't valid.

Update NumPy.
pip install numpy --upgrade
It works for me!

This one worked for me:
pip install -- pywin32==227

I faced the same issue when I uninstalled and reinstalled a different version of 2.7.x of Python on my system using a 32-bit Windows Installer. I got the same error on most of my import statements.
I uninstalled the newly installed Python, downloaded a 64-bit Windows installer, reinstalled Python again, and it worked.

So I had problems installing vtk under Windows (as I use Python 3.7, there isn't any binary available so far. Just for older Python versions pip install vtk is not working)
I did wrote Python in my cmd:
Python 3.7.3 on win32
So I now know I have Python 3.7.3 running on a 32 bit.
I then downloaded the correct wheel at VTK‑8.2.0‑cp37‑cp37m‑win32.whl
Next I installed that wheel:
pip install VTK-8.2.0-cp37-cp37m-win32.whl
Then I tested it and it worked:
python
import vtk

I experienced the same problem while trying to write code concerning speech-to-text.
The solution was very simple. Uninstall the previous pywin32 using the pip method:
pip uninstall pywin32
The above will remove the existing one which is by default for 32 bit computers. And install it again using
pip install pywin32
This will install the one for the 64 bit computer which you are using.

I had a similar issue while trying to run uvicorn,
Creating a new virtual environment and reinstalling the python packages worked

You can install opencv from official or unofficial sites.
Refer to this question and this issue if you are using Anaconda.

It has a very simple solution.
After installing opencv
place
cv2.pyd from C:\opencv\build\python\2.7\ **x64** to C:\Python27\Lib\site-packages
instead of, place cv2.pyd from C:\opencv\build\python\2.7\ **x86** to C:\Python27\Lib\site-packages

I got this error when trying to import MySQLdb.
What worked for me was to uninstall Python and then reinstall it.
I got the error after installing npm (https://www.npmjs.com/get-npm). One thing it did was install Python even though I already had it.

First I copied cv2.pyd from /opencv/build/python/2.7/x86 to C:/Python27/Lib/site-packeges. The error was
"RuntimeError: module compiled against API version 9 but this version of numpy is 7"
Then I installed numpy-1.8.0-win32-superpack-python2.7.exe and OpenCV works fine.
>>> import cv2
>>> print cv2.__version__
2.4.13

Please make sure that you have installed a Python 2.7.12 or below version. Otherwise you will definitely get this error.
Make sure the Oracle client is 64 bit installed if the OS is 64 bit.
Make sure the Microsoft Visual C++ compiler for Python 2.7 is 64 for bit for a 64 bit OS or 32 bit for 32 bit.
Note: If your OS is 64 bit, install all packages of 64 bit or if the OS is 32 bit, install the 32-bit package.

This has worked for me. I have tried different methods, but this was my best solution.
Open a command prompt and type the following;
pip install opencv-python
(Make sure your Internet connection is on.)
After that, try importing it again.

It could also be that your Anaconda version is 32 bit when it should be 64 bit.

If you are using pycharm I go to settings -> python interpretation and click the + button and search for the name on the list of python packages there

I found the solution. Maybe you can try to use the cmd window rather than the Anaconda prompt window to start your first Scrapy test.

ImportError: No module named twisted.persisted.styles

From IDLE, I tried to run a script with a newly installed scrapy 1.0.3.
I'm using a script from a friend whom it worked for (but on Windows, I'm on a Mac).
From the import of scrapy on the first line, I get this error when running the program:
ImportError: No module named twisted.persisted.styles
The whole script, if it's helpful, points to this:
Traceback (most recent call last):
File "/Users/eliasfong/tutorial/tutorial/spiders/medspider.py", line 1, in <module>
import scrapy
File "/Library/Python/2.7/site-packages/scrapy/__init__.py", line 27, in <module>
from . import _monkeypatches
File "/Library/Python/2.7/site-packages/scrapy/_monkeypatches.py", line 20, in <module>
import twisted.persisted.styles # NOQA
ImportError: No module named twisted.persisted.styles
Any suggestions on how to tackle this problem?

Just try to force the update of twisted :
pip install twisted --upgrade
That works for me with python3.4 and Scrapy==1.1.0rc1

Either twisted is installed on your mac (I highly doubt it since it's not a standard library) and for whatever reason the IDE (i'm assuming that's what you mean since you typed "idle") or the terminal you are in doesn't have your updated environment variables, meaning it doesn't understand where your default python libraries are (again I highly doubt it), or you simple do not have twisted installed on your mac. If it's not installed you have a couple of options:
The easiest way to install a python package is through pip.
If that not an option you can try homebrew which is another package manager for macs. It offers an easy way to install packages correctly.
If that still is not an option for you or you simply don't want to attempt that you can download twisted directly from here (the .bz2 since you're on a mac), click on it and it should unzip it for you. Then just run setup.py and it should install it in the correct location on your mac.
If that still doesn't work and you have decent knowledge of unix. Use the "locate" command on the terminal and find out where your dist-packages directory is and put the source for twisted in there directly and then attempt to import twisted in your IDE or in the python interpreter to verify that it is installed.
note: If you're still having problems after it is installed trying restarting your IDE or messing with some setting to make sure your IDE has the right environment and python path. Hope that helps!

It could be related to having installed Python without bzip2. I had the same error and this helped me, see the accepted answer here:
Installing Twisted through pip broken on one server

Had this exact thing on FreeBSD. Solution (as root/sudo):
chmod -R go+rX /usr/local/lib/python2.7/site-packages
Some directory permissions weren't set up right on install.
