Hello everyone.Today,I am going to share how to use Python3 and Python2 with pip support on Windows OS.If you try to install latest Python version 3.6 ,it provides you the option of adding Python 3.6 to PATH ,but this is not provided by Python2 installer still.Many users may find it difficult to use both version with corresponding pip on Windows OS.
So,I am sharing this method which helped me to use Python2 and Python3 simultaneously.
STEPS
1.Download Python3 and Python2 installer from python.org .
2.Run Python3 installer and tick(enable) "Add Python 3.6 to Path" as shown in screenshot so that you can run Python3 by python command on Terminal/Shell.
3.You can run Python3 by using python command and its pip by using pip command.
4.Run Python2 installer and install Python2 .
5.Now ,you need to edit system environment variable PATH as shown in screenshot below for using Python2 and its pip2 in Terminal/shell :
6.Click on Edit Button .After that all the enteries of PATH variable will be displayed.Now,click on New Button and add this entry as shown in screenshot:
C:\\Python27\\Scripts
7.Click on OK button to save and make it sure that the entry added to PATH varaiable is not C:\\Python27. Otherwise, python command will run Python2 instead of Python3 .
8. Again add a new entery PY_PATH to system variables and set its value to 2 if you want to run python2 by using py command.
9.Now, you can use Python 3 by using python or py -3. You can use pip for python 3 by pip or pip3 command .You can use Python2 by using py command or py-2command .You can use pip for Python2 by using pip2 command.(See Screenshot)
If every step is followed correctly,you will see Python3 and Python2 running successfully with pip support in Terminal.
If you have any query or you need help,post in comments.I will be glad to help you.
Thanks for reading my post.I hope my post will be useful to Python users who are using Windows OS.
