为什么在py运行时python命令没有在powershell中调用python解释器

Question

I am using windows 10 operating system. I had downloaded and installed Ananconda python 3.6 version for windows 64 bit.

I had added Anaconda to windows path manually. The current path is as below.

I have also added the PYTHONPATH variable.

The command py launches the python interpreter as below.

But the command python fails with below error.

How do I fix the issue. I am trying to run a simple hello World on sublime text but the same is failing with below error.

'python' is not recognized as an internal or external command,
operable program or batch file.
[Finished in 0.0s with exit code 1]
[shell_cmd: python -u "D:\Python_Test\testprinting.py"]
[dir: D:\Python_Test]

Answer 1

I could not figure out the exact reason why python was not being recognized as a command even thought the path C:\\ProgramData\\Anaconda3\\ was added to the path variable with and without quotes "". I reinstalled the Anaconda3 package and then manually added the path. This time python command invokes the interpreter and its working fine in sublime text.
