You know what has worked for me really well on windows.
My Computer > Properties > Advanced System Settings > Environment Variables >
Just add the path as C:\Python27 (or wherever you installed python)
OR
Then under system variables I create a new Variable called PythonPath. In this variable I have C:\Python27\Lib;C:\Python27\DLLs;C:\Python27\Lib\lib-tk;C:\other-folders-on-the-path
This is the best way that has worked for me which I hadn't found in any of the docs offered.
EDIT: For those who are not able to get it, Please add
C:\Python27;
along with it. Else it will never work.

Windows 7 Professional I Modified @mongoose_za's answer to make it easier to change the python version:
- [Right Click]Computer > Properties >Advanced System Settings > Environment Variables
- Click [New] under "System Variable"
- Variable Name: PY_HOME, Variable Value:C:\path\to\python\version
- Click [OK]
- Locate the "Path" System variable and click [Edit]
Add the following to the existing variable:
%PY_HOME%;%PY_HOME%\Lib;%PY_HOME%\DLLs;%PY_HOME%\Lib\lib-tk;
Click [OK] to close all of the windows.
As a final sanity check open a command prompt and enter python. You should see
>python [whatever version you are using]
If you need to switch between versions, you only need to modify the PY_HOME variable to point to the proper directory. This is bit easier to manage if you need multiple python versions installed.
- Hold Win and press Pause.
- Click Advanced System Settings.
- Click Environment Variables.
- Append
;C:\python27to thePathvariable. - Restart Command Prompt.
When setting Environmental Variables in Windows, I have gone wrong on many, many occasions. I thought I should share a few of my past mistakes here hoping that it might help someone. (These apply to all Environmental Variables, not just when setting Python Path)
Watch out for these possible mistakes:
- Kill and reopen your shell window: Once you make a change to the ENVIRONMENTAL Variables, you have to restart the window you are testing it on.
- NO SPACES when setting the Variables. Make sure that you are adding the
;C:\Python27WITHOUT any spaces. (It is common to tryC:\SomeOther; C:\Python27That space (␣) after the semicolon is not okay.) - USE A BACKWARD SLASH when spelling out your full path. You will see forward slashes when you try
echo $PATHbut only backward slashes have worked for me. - DO NOT ADD a final backslash. Only
C:\Python27NOTC:\Python27\
How to add python to path and how to use it in commandline/powershell?
Python - add PYTHONPATH during command line module run - Stack Overflow
what does it mean to " Add python<version> to PATH " ?
What if you forget to add Python to PATH?

For Windows 10/8/7:
- Open
System Properties(Right clickComputerin the start menu, or use the keyboard shortcut Win+Pause) - Click
Advanced system settingsin the sidebar. - Click
Environment Variables... - Select
PATHin theSystem variablessection - Click
Edit Add Python's path to the end of the list (the paths are separated by semicolons). For example:
C:\Windows;C:\Windows\System32;C:\Python27
For Windows XP:
- Open
System Properties(Type it in the start menu, or use the keyboard shortcut Win+Pause) - Switch to the
Advancedtab - Click
Environment Variables... - Select
PATHin theSystem variablessection - Click
Edit Add Python's path to the end of the list (the paths are separated by semicolons). For example:
C:\Windows;C:\Windows\System32;C:\Python27Test on a new terminal window or if using an integrated terminal within a text editor, close and restart your editor or the changes won't be applied.
For anyone trying to achieve this with Python 3.3+, the Windows installer now includes an option to add python.exe to the system search path. Read more in the docs.
So the answer I've been getting is add python to environment variables which I have done
But I still get the error when running from user/downloads
python -c "from pdf2docx import Converter"
The system cannot execute the specified program.
p.s why are we banning images makes things so much more complicated?
For Mac/Linux;
PYTHONPATH=/foo/bar/baz python somescript.py somecommand
For Windows, setup a wrapper pythonpath.bat;
@ECHO OFF
setlocal
set PYTHONPATH=%1
python %2 %3
endlocal
and call pythonpath.bat script file like;
pythonpath.bat /foo/bar/baz somescript.py somecommand
import sys
sys.path.append('your certain directory')
Basically sys.path is a list with all the search paths for python modules. It is initialized by the interpreter. The content of PYTHONPATH is automatically added to the end of that list.

asking bc i am installing python and i wanna know what will happen if i don't really click on the checkbox
If you forget to add Python to the PATH, you won't be able to run Python in your command line from any other directory.
You will get a message saying,
'python' is not recognized as an internal or external command.
This is because Windows is trying to search for Python in its PATH variable and is unable to find it.
Here is a step-by-step instruction to add Python to the PATH variable in Windows 10.
-
Copy the directory to which Python is being installed.
-
Search for System Properties in the Search Bar.
-
Click on the "Environment Variables" button in System Properties.
-
Click on the "Path" variable and then click on "Edit".
-
Now here's the deal. Pay Attention! Paste the directory path from Step 1 at the top of the list. You can use the "Move up" button to get it to the top. Now click on "Ok".
Now you can open up your command line and run python. The Python interactive shell will open up.
*Here is a little extra tip! *
Add the Scripts folder to the PATH variable too. This is the folder where all your libraries will be installed.
If the instructions are not clear enough for you, you can also check out the visual guide containing images of every step, on my blog for achieving the above objective.
Good luck and let me know!
Do you remember checking the box in the image shown below to add your Python installation to PATH in Windows 10?
Adding Python to PATHWell, I was curious! What if someone accidentally forgot to check that little radio button? What would be the possible recovery steps?
So I spent my evening yesterday uninstalling Python and re-installing to figure out a way to add Python to the PATH post-installation.
If you forget to add Python to the PATH variable, you won't be able to run Python in your command line.
You will get a message saying,
‘python' is not recognized as an internal or external command.
Here are the steps I used to add Python to the PATH variable in Windows 10.
-
Copy the directory to which Python is being installed.
-
Search for System Properties in the Search Bar.
-
Click on the "Environment Variables" button in System Properties.
-
Click on the "Path" variable and then click on "Edit".
-
Now here's the deal. Paste the directory path from Step 1 at the top of the list. You can use the "Move up" button to get it to the top. Now click on "Ok".
I found out that if you paste the path at the end, it still doesn't work. Can someone tell me why?
Anyways, if the steps are not clear to anyone, here is a visual guide containing images of every step, on my blog for achieving the above objective. If you are interested, do take a look.
