How can I run a python script in Terminal on Mac without using the "python" keyword, without having to edit my existing python files?
Right now I have to do this:
python script.py
What I like to do is this:
script.py

Add a shebang:
#!/usr/bin/python
or
#!/usr/bin/env python
I prefer the second one, since Python can be anywhere like /usr/bin/python, /usr/local/bin/python etc. and second one ensure that you don't have to keep editing the shebang.
And then you can just execute it as ./script.py if it is executable.

Will this trick work on the windows machine as well ?
in your python script add this as your first line
#!/usr/bin/python
then in terminal do this chmod +x ./yourpythonscript.py
then from terminal execute as ./yourpythonscript.py

@mofle nope sorry you can't make a file executable in unix system without specifying what file will execute it

I dont know about how but it might be possible on a Mac to associate an extension or a mime type to a handler (e.g. open all files of type .py with python) etc. Then you can do it without modifying your source files.

Actually, you can make a text file executable - but the system will then use your shell (probably bash) to execute it. Also,
#! /usr/bin/env python is marginally more portable as it doesn't hardcode where python is.Try ./script.py instead of script.py ... or ensure your current directory is in your path and script.py should work....

thanks, this helped. I was trying to run with just script.py in the command line and it was giving me
command not found.
