I'm trying to install the os Python module on Windows.
In a cmd console, I typed:
C:\Users\username> pip install os
Collecting os
Could not find a version that satisfies the requirement os (from versions: )
No matching distribution found for os
So I guessed the module was not available on Windows for some reasons, but I found references of it in some SO questions.
Obviously, typing Windows and os in Google only gives me answers about Windows itself.
So, how can I install the os module on Windows?

OS is python's standard library. So no need to download it.

I had python 3.7.7 32bit installed on my laptop. I installed pip and pythonnet.
I have this line of code in my python project which is executing fine.
import sys, os, clr, time
from pathlib import Path
Now I have installed python 3.7.7 64bit version on my laptop. Before running the application, I changed the current python environment to point to 64bit. Upon changing the env, I'm getting the error :
No module named 'clr'
Do I have install pythonnet again for 64bit. If yes, how to do it again? Because when I try to install again it says
Requirement already satisfied: pythonnet in
c:\users\XXXXXX\appdata\local\programs\python\python37-32\lib\site-packages
(2.5.2) Requirement already satisfied: pycparser in
c:\users\XXXXXX\appdata\local\programs\python\python37-32\lib\site-packages
(from pythonnet) (2.21)
It is referring to python37-32 still. How do I target it to python37 (64bit).
I have stumbled into this issue a lot with my classmates in programming classes. The problem is that different programs point to different versions of Python. Assuming you're using VS Code, you are able to change which Python version to use, by the "Python: Select Interpreter" command.
Assuming you're using the terminal, you can change which Python version to use when you type "python", by changing your PATH environments.
I need the pickle package installed under my Python 3.9 under Windows 10.
What I tried
When trying with pip install pickle I was getting:
ERROR: Could not find a version that satisfies the requirement pickle
(from versions: none) ERROR: No matching distribution found for pickle
Then I tried the solution suggested in this question using pip install pickle5 but got the following error:
error: Microsoft Visual C++ 14.0 or greater is required. Get it with "Microsoft C++ Build Tools": https://visualstudio.microsoft.com/visual-cpp-build-tools/
I then tried to install the Tool suggested by the error but got same error message after trying again pip install pickle5.
Question
Which is the correct way to install pickle package under Python 3.9 in Windows 10?
UPDATE
There is no need to install pickle module as it comes already installed along with Python 3.x. Just needed to do import pickle and voila!
Cedric UPDATED answer is right. Pickle exists within Python 3.9. You don't need pip install pickle. Just use it.
import pickle
I found a way that I'm not sure it's the optimal but it works.
I did pip install pickle4
And then in the script just
import pickle4 as pickle
UPDATE
There is no need to install pickle as it's already within Python 3.9. Just needed to import pickle and voila!
For Generalized Summary, for almost all Python versions, you never need to worry for installing 'pickle' as it comes already installed with the python interpreter.
Hence, simple import works:
import pickle
In case this doesn't work, refer to Pickle Install Problems on Stack Overflow.
Another suggested way is to run: pip install pickle-mixin
For other Queries and Info, refer to Python Pickle Documentation.
My python version is Python 2.7.17
I usually use pip to install other modules like shutil and itertool etc. I can't find the package name for os, getopt and sys modules.
Any help will be appreciated.
Thank you.
Python 2.7 is obsolete and no longer supported (as of 1 January 2020). You should consider using the latest version (currently Python 3.8.5). For more information, see this.
The modules you are looking for are core modules of standard Python distribution, therefore they are installed when installing Python itself.
They are installed with your python as part of the standard library, if they are missing, something is wrong with your Python installation and you should reinstall it
I've been trying for a couple of hours already. It seems IDLE can't find any third-party module. I am a Python beginner.
Here is some info about my system:
OSX version: 10.11.5
python version: Python 2.7, Python 3.4, Python 3.5
The initial installation using pip (among other methods) seems to work fine. When I repeat the installation, terminal responds with:
Requirement already satisfied (use --upgrade to upgrade): pyperclip in
./anaconda/lib/python3.4/site-packages
However, when I go to IDLE (Python 3.4) and try to import the module, IDLE responds with:
Traceback (most recent call last): File "", line 1, in
import pyperclip ImportError: No module named 'pyperclip'
I have read that it may have something to do with my PATH or some virtual environment. I’ll be frank, I’m not sure what to make of these as they seem beyond my current ability.
This inability to import modules is becoming an almost insurmountable roadblock to advancing with Python. If you can offer any ideas on what I can do or can ELI5 the solution, I am forever in your debt?
It seems you are using conda, but you are trying to install the pyperclip module with pip. Have you tried running conda install pyperclip?
As stated here:
Because Conda introduces a new packaging format, you cannot use pip and Conda interchangeably; pip cannot install the Conda package format. You can use the two tools side by side but they do not interoperate either.
In Python 3.4 from Anaconda, I created a program and it is giving me and import error each time I run it.
Using Spyder.
ImportError: No module named 'win32api'
I already have the pywin32 installed. And I can see the win32api.pyd under C:\Anaconda3\Lib\site-packages\win32
This is the import code on my program:
from tkinter import *
from tkinter import ttk
import tkinter.messagebox
import time
import requests #needs to be installed
import pymysql #needs to be installed
import csv
import win32com.client #needs to be installed
import datetime
This is the whole error:
File "C:\Anaconda3\lib\site-packages\win32com\__init__.py", line 5, in <module>
import win32api, sys, os
ImportError: No module named 'win32api'
This is the only instance of Python I have installed. I uninstalled everything else and installed only Anaconda.
Searching online I got to something that said that it could be a problem with the PYTHONPATH. But honestly, I have no idea what they are talking about.
So any noob help would be really appreciated.
I am using Windows 7 by the way.
Thank you
The installation for pywin32 must have failed, or it is not for same OS bit architecture (say anaconda 64 bit and pywin32 32 bit). I recommend
you uninstall pywin32,
check what bit version of anaconda you are using, then
install pywin32 for same version,
verify that the installer indicates 100% success and there are no errors flagged in the installer's log window (it's rare but something may fail and the installer doesn't know).
Then open a python console and type "import win32com".
If #5 fails to import win32com, then:
try installing a different version of python, for example from python.org
repeat steps 2 to 5 above but for new python instead of anaconda
Could be that anaconda distributors did something to the python interpreter (although I didn't think so), or that some libs aren't registered right (see answer https://stackoverflow.com/a/17061853/869951 for some more things to try).
This should work:
pip install pypiwin32
I had the same problem and solved it installing the module pywin32:
In a normal python:
pip install pywin32
In anaconda:
conda install pywin32
My python installation (Intel® Distribution for Python) had some kind of dependency problem and was giving this error. After installing this module I never more saw it.
As mentioned by outforawhile in comment, simply restarting the laptop fixed this for me.
It may be that this is required for Windows to register the DLL.
try this before install pywin32
pip install pywinutils
