Adding external library to Pycharm when using Python in ArcGIS [duplicate]

This question already has answers here:
"python" not recognized as a command
(14 answers)
Closed 2 years ago.
So I have recently installed Python Version 2.7.5 and I have made a little loop thing with it but the problem is, when I go to cmd and type python testloop.py I get the error:
'python' is not recognized as an internal or external command
I have tried setting the path but no avail.
Here is my path:
C:\Program Files\Python27
As you can see, this is where my Python is installed. I don't know what else to do. Can someone help?

Try "py" instead of "python" from command line:
C:\Users\Cpsa>py
Python 3.4.1 (v3.4.1:c0e311e010fc, May 18 2014, 10:38:22) [MSC v.1600 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

I have found the answer... click on the installer and check the box "Add python to environment variables" DO NOT uninstall the old one rather click on modify....Click on link for picture...

You need to add that folder to your Windows Path:

If you want to see python version then you should use py -V instead of python -V
C:\Users\ghasan>py -V
Python 3.7.1
If you want to go to python's running environment then you should use py instead of python
C:\Users\ghasan>py
Python 3.7.1 (v3.7.1:260ec2c36a, Oct 20 2018, 14:57:15) [MSC v.1915 64

Type "help", "copyright", "credits" or "license" for more information.
Here you can run the python program as:
print('Hello Python')
Hello Python

Firstly, be sure where your python directory. It is normally in C:\Python27. If yours is different then change it from the below command.
If after you install it python still isn’t recognized, then in PowerShell enter this:
[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27",
"User")
Close PowerShell and then start it again to make sure Python now runs. If it doesn’t,
restart may be required.

Type py -v instead of python -v in command prompt

i solved this by running CMD in administration mode, so try this.

Open CMD with administrative access(Right click then run as administrator) then type the following command there:
set PYTHONPATH=%PYTHONPATH%;C:\My_python_lib
Replace My_python_lib with the folder name of your installed python like for me it was C:\python27.
Then to check if the path variable is set, type echo %PATH% you'll see your python part in the end. Hence now python is accessible.

I have installed python 3.7.4. First, I tried python in my command prompt. It was saying that 'Python is not recognized command......'. Then I tried 'py' command and it works.
My sample command is:
py hacker.py

I have met same issue when I install Python, and it is resolved when I set a PATH in system, here are the steps.
Navigate to "Control Panel" -> "System"
Click "Advanced system settings" on the left
Click "Environment Variables"
Search and click "Path" variable
Click "Edit"
Add "C:\"to the environment variables field, if you are using Windows7, then separate it by a semicolon from the existing entry. If you are using Windows10, just simply click "New" to add.
Reopen the Command Prompt and try
enter image description here

From the Python docs, set the PATH like you did as above.
You should arrange for Python’s installation directory to be added to the PATH of every command window as it starts. If you installed Python fairly recently then the command dir C:\py* will probably tell you where it is installed; the usual location is something like C:\Python27. Otherwise you will be reduced to a search of your whole disk
Use Tools ‣ Find or hit the Search button and look for “python.exe”. Supposing you discover that Python is installed in the C:\Python27 directory (the default at the time of writing), you should make sure that entering the command
Then execute the Python command using the full path name to make sure that works.

Another helpful but simple solution might be restarting your computer after doing the download if Python is in the PATH variable. This has been a mistake I usually make when downloading Python onto a new machine.

If you uninstalled then re-installed, and running 'python' in CLI, make sure to open a new CMD after your installation for 'python' to be recognized. 'py' will probably be recognized with an old CLI because its not tied to any version.

Option 1 : Select on add environment var during installation
Option 2 : Go to C:\Users-> AppData (hidden file) -> Local\Programs\Python\Python38-32(depends on version installed)\Scripts
Copy path and add to env vars path.
For me this path worked : C:\Users\Username\AppData\Local\Programs\Python\Python38-32\Scripts

It was a bit more confusing with the Python instructions once SQL Server 2019 was installed with Python. The actual path I find is as follows:
C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64
Scripts run with an Execute command:
Declare #script nvarchar(max)=N'print(11-2)' execute sp_execute_external_script #language = N'Python', #script = #script
There is additional documentation in reference to SQL 2019's version of Python. There is a statement that recommends PIP be used only from a download of sqlmutils-x.x.x.zip located on git (https://www.github.com/Microsoft/sqlmutils) But there is a caveat. Currently this only works for R and not for Python (Anaconda and consequently pip). Python over SQL works but pip is not yet available. (11/25/2019)

os x, python, homebrew -> something weird going on

hoping someone can help me out. I followed a couple of guides about setting up a new machine for python development. (one) (two)
I followed pretty much everything but I am really confused about the changes to my .bash_profile
When I comment out export PATH=/usr/local/bin:$PATH in .bash_profile and type which python into terminal, I see what I expect.
which python
/usr/local/bin/python
python
Python 2.7.11 (default, Jan 22 2016, 08:29:18)
[GCC 4.2.1 Compatible Apple LLVM 7.0.2 (clang-700.1.81)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
What is happening in bash_profile, how come it doesn't matter if I comment everything out, save it, and run the commands?
More importantly, how do I get to my default install of python and make sure it is still there and unaffected? Am I correct in understanding that the above version is the python installed by Homebrew?

.bash_profile is read only when the Bash shell is loaded, so changing this file after the shell has been loaded doesn't affect it. To see the changes after modifying and saving the file, you need to restart the shell or run source ~/.bash_profile.
Modifying the PATH environment variable doesn't affect the Python itself, it only modifies where it's searched first to be executed, when you will run python .... E.g., if you have python installed in /a/python and /b/python, then:
if your PATH is set to /a/python:/b/python:$PATH and you run python ....py actually the /a/python ....py is executed;
if your PATH is set to /b/python:/a/python:$PATH and you run python ....py actually the /b/python ....py is executed.
If you didn't modified the PATH (e.g. but executing something like export PATH=/usr/local/bin:$PATH in the shell or adding it to .bash_profile), then executing which python should show the default python path.
In the case you described, it shows you the python, that you set it to use by modifying the PATH. To see the default one, comment the export... string, save the .bash_profile file and either run source ~/.bash_profile or restart the shell, and only then see the which python output.

How to switch to python2 in a particular terminal window temporarily?

I have a big third-party python2.7 application, a bunch of python scripts, which is added into PATH and it requires python2.7 instead of python 3.5 which I have by default.
$ python
Python 3.5.1 (default, Mar 3 2016, 09:29:07)
[GCC 5.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
$ python2
Python 2.7.11 (default, Mar 3 2016, 11:00:04)
[GCC 5.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>>
I run that application as $ some_app arg1 arg2. How can make it use python2 as a temporary solution, preferably only in that single terminal window?
I don't substitute a call of that application with "python". I call it like $ some_app arg1 arg2. I don't want to change the version of python permanently or modify the source code of the application.

My favorite way: use virtualenv or pyenv
The most used tool for keeping multiple Python environments is virtualenv. I like to use a sugary wrapper around it called virtualenvwrapper.
Usually I install it using:
sudo pip install virtualenvwrapper
Then I add a line like the following one to my shell profile:
source /usr/local/bin/virtualenvwrapper.sh
Now you can make a virtual environment for each version of Python. Gosh, you can make one for each Python project!
mkvirtualenv py3
mkvirtualenv py2 --python=python2
Then you can switch temporarily to python2 by typing:
workon py2
There is another tool called pyenv that lets you easily switch between multiple versions of Python. Quoting the project readme, "It's simple, unobtrusive, and follows the UNIX tradition of single-purpose tools that do one thing well. This project was forked from rbenv and ruby-build, and modified for Python". Looks like it is getting popular.
Both are elegant, easy to use and a perfect fit for this use case (switch to a particular python version in a terminal window temporarily).
The Unix way: set $PATH
It is a best practice to write the shebang for Python scripts like:
#!/usr/bin/env python
If the 3rd-party app you are running follows this convention, you can change the PATH. For example, suppose the default python interpreter is not the one you want:
$ env python --version
Python 3.5.1
Make a local copy of the python you want to make the default temporarily (you just have to do this one time):
$ mkdir ~/local
$ mkdir ~/local/python2
$ ln -s `which python2` ~/local/python2/python
Then every time you want to make python2 the default, do:
$ export PATH=~/local/python2/:$PATH
Now the default is the version you want:
$ env python --version
Python 2.7.10
The positive karma way: if the 3rd-party app has a hardcoded path in the shebang
Perhaps the app author did not follow the best practices and hardcoded the Python path in the shebang. For example, suppose the first line of the program is:
#!/usr/bin/python
In this case, none of the previous tricks would work. Personally, I would change it to the canonical form and send a pull request to the author of the 3rd-party app.
The bossy way: change the default Python version system-wide
While this does not really answer your question - because it affects every window and avery other user in the system - I'm mentioning it for the sake of completeness.
For example, if you are using Ubuntu you can change the default python interpreter using:
$ update-alternatives --config python
Other Linux distributions probably have something like this.
Quick and dirty
The shebang just tells the shell to call the script using the given interpreter. You can override the shebang when calling the app as interpreter app:
$ python2 `which app_name`
Or:
$ python2 /path/to/app_name
You can also just edit the program and change the shebang:
#!/usr/bin/python2
Note that this would change permanently the Python interpreter for that program, it is not temporary nor restricted to a particular terminal. Worst, if the program is in the global PATH, all the other users of the system will be affected. If you want to restore the old behavior, you must undo your changes.
That said, sometimes you just don't care about doing it right, you just want to make it work.

You can make use of terminal alias. The alias will not be temporary but it will not affect your system, so you can have a short alias like:
alias pyt "/usr/bin/python2.7"
in your .bashrc file inside home directory

As the question is tagged with Linux, I assume your scripts starts with that line
#! /usr/bin/env python
This is great to allow the system to choose the current Python installation, but here your requirement is to specifically use version 2.7
So IMHO you just have to change the hashbang line to select the required version:
#! /path/to/python-2.7

If you are using Anaconda as your Python distribution, it has virtual enviroments built in. If not, use virtualenv and virtualenvwrapper as Paul recommended.
In addition I recommend autoenv. With that you can automatically change your venv depending on the folder you're in. There is one for bash and one for zsh.
