Use inspect:

import inspect


def fun_one(x):
    print(x)

with open('file.py', 'a') as f:
    f.write(inspect.getsource(fun_one))

Your file.py will contain:

def fun_one(x):
    print(x)

Also, note that you don't need quit() and that you can open and close the file using with.

That being said, I remain curious about why you would need such thing.
