Using Python3 and Python2 on Windows OS with pip support

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.


1.Download Python3 and Python2 installer from .

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:




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-2 command .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.

Fixing script to run Python in Terminal on all Android OS in an easier way by using command or by any custom command

Hello,everyone.Today, I am going to share how to fix my old script which I had shared on my blog for using Python in Terminal and how to use command after fixing that.

At first,I would like to thank my friend Luiz who fixed the old script which I had shared with you all on this blog.

I consider that Python For Android  app and its Python library has been already installed by you.If,you are using my old script  which you have already copied to /system/bin ,set its permission as 777,and try to run Python in Terminal  with this command:  ,you will get error as shown in the screenshot:

This error is shown due to an error in first line of script as shown in screenshot:

#! /bin/sh 

You are able to use Python only by using this command which is long and complex to type:

sh /system/bin/

*Fixing  file:

Android executes commands from /system/bin or /system/xbin .So,we need to edit the first line of script of /system/bin  directory as shown below in screenshot:

# !/system/bin/sh 

Save the file and check that it’s permission is assigned as 777.

Or,you can download my  fixed file from below.

Download Here:

Now,open Terminal app and use this simple command to run Python  as shown in screenshot:

You can see Python running successfully on your Terminal.If you get any error,there might be some mistakes.You need to check your all steps carefully.T o run any file in current directory,you need to use this command:

*Customising(Renaming) command to any desired name 

You can also rename file of /system/bin directory to whatever name you like . you need to remember that name and use that name as command to run Python.For example,I have renamed to gaurav as shown in screenshot:

Now,open Terminal app,and use the command gaurav (you use the name whatever you have given to file) ,you will see Python successfully running with your customised command as shown in screenshot:

You will see Python running successfully if everything is fine.Now,You have successfullychanged/customised command.You need to use that command every time to run Python.

Thanks everyone for reading this post.If you have any questions or you get any error,please post in Comments.

Using Python in Terminal on Android OS  without Root Access

Hello,everyone.Today,I am going to share how to use Python in Terminal on Android phone without Root Access.This post is made for them who do not use Rooted phone or those who do not want to Root.

I had thought that it would not be possible to use Python in Terminal without Root Access.Python scripts can also be run using Sl4A , but I find using Python in Terminal better as Sl4a has no option of changing directory.Running Python files is easier in Terminal.So,let us proceed to the tutorial.

Tools Required: 

1. Python For Android.apk: Download Here

2.Terminal.apk :  Download Here

3. Download Here

4. Sl4A.apk(optional file): Download Here 

1.Download all of the above files if you do not have.Install Python For Android app. You can also install Sl4A app if you want.

2.Open Python For Android app and click on Install button to install Python library on your phone .Internet is required for first time installation.After successful installation of Python library,your screen should be like as shown in screenshot given below:

3.Now,copy file to your internal memory sdcard  as shown in the screenshot.

3.Now,open Terminal app.To run Python,type these carefully as shown in screenshot:

sh  /sdcard/ 

4.If everything is fine,you will see Python successfully running on Terminal.If,you get error as file not found,make sure that is there in internal sdcard(/sdcard ).

5.To run a script file say of folder scripts in your sdcard(/sdcard/scripts folder) as shown in screenshot:

we need to type the following command carefully to run file( /sdcard/scripts/ ) as shown in screenshot below :

cd /sdcard/scripts

sh  /sdcard/

6. In this way you can run any Python file present in current directory on Terminal app by using the following command:

sh  /sdcard/

Now,you can use Python and Python Scripts on all  Android OS without Root Access in the way shown above.Tutorial is complete now.

I hope this tutorial will be useful for many users.Thanks everyone for reading my post.
