set path for command line of python (mac)

Question

I defined some command line tools of python (take mycmd.py as an example), and saved them in the folder ~/Scripts. Hence, I have to type (for example) python /Scripts/mycmd.py -o v. It is tedious to repeat the name of the folder /Scripts. I want to run the command only inputting python mycmd.py -o v, even without cd. How should I do? Add a path to the original one?

PS: in mac

Maybe there's a better solution:

put the ~/Scripts folder in your PATH.
make sure that your scripts have the correct shebang for python (ex: #!/usr/bin/env python3, more details in Should I put #! (shebang) in Python scripts, and what form should it take?)
make your scripts executable (chmod a+x ~/Scripts/*.py)

Then you can call your scripts like any other tool (without python prefix), ex:

mycmd.py -o v

On Windows, you don't even need a shebang, since .py files are seen as launchable files, associated with the installed python interpreter. Putting the dir in the path is enough.

this will not work . python running from shell from what i understand - op meant, manipulating PTHONPATH will not help in this case – ddor254 Apr 09 '18 at 09:04
@AbhishakeGupta ddor is right. I set PYTHONPATH in ~/.zshrc, but it did not work. – William Song Apr 09 '18 at 09:11
add the full absolute path to that directory. – Abhishake Gupta Apr 09 '18 at 09:15
