如何通过在Windows中选择anaconda或Python从命令提示符运行Python文件？

Question

I have installed Anaconda with Python version 3.x and I have already installed native python 3.6.4. I wanted to run my python script from the command prompt either using anaconda or native python according to my need.

I tried to run Python script from command prompt but it is actually using anaconda's python instead of the native one.

My native python is installed in C:/users/user_name/Appdata/local/programs/python/python36

How should I installed anaconda or what steps can I take.

I didn't set any environment variables. I don't prefer that also.

First of all, you should update Python to at least 3.7.

On the first line of your script put this shebang:

#!/usr/bin/env python3

This is for Unix but I understand it works for Windows also. For more detail on shebangs, check here .

On Windows, the standard Python installer already associates the .py extension with a file type (Python.File) and gives that file type an open command that runs the interpreter (D:\\Program Files\\Python\\python.exe "%1" %*). This is enough to make scripts executable from the command prompt as foo.py. If you'd rather be able to execute the script by simple typing foo with no extension you need to add .py to the PATHEXT environment variable.
