If you literally mean how to write,save and use a Python function (from within another script) then I'll have a go:
How to save and run a bash script: Write your script
Same with Python, create a text file with your favourite editor and save it with a .py extension. This is now a Python module that you can import into any other script. Lets assume you called it mymodule.py.
save it in the normal manner
Yes, gotta do that with Python too.
chmod to x for everyone you want to be able to execute it. (E.g. where owner is root: perhaps 744)
You don't need that for a Python module, it only needs to be readable. (But if you do make it executable you can add a shebang line at the top and then run it directly from the command prompt. But since you only want to access the functions within we won't need to do that.)
Either move the file into a directory on your path, or add the directory that the file is in to your path.
Either save the file in a directory in your PYTHONPATH or add the directory you saved it in to your PYTHONPATH
It will now run.
It can now be imported. So to use your function, let's call it spam(), in your mymodule.py file: Create a new python script, lets assume its called myfile.py. add the line import mymodule call the function with myVariable = mymodule.spam() Save your new Python script file Execute your new file from Pyhon with $ python /full/path/to/myfile.py There is a full worked example in the Functions and Modules topic in my tutorial...
