python – What is the best way to call a script from another script?

The usual way to do this is something like the following.

test1.py

def some_func():
    print in test 1, unproductive

if __name__ == __main__:
    # test1.py executed as script
    # do something
    some_func()

service.py

import test1

def service_func():
    print service func

if __name__ == __main__:
    # service.py executed as script
    # do something
    service_func()
    test1.some_func()

This is possible in Python 2 using

execfile(test2.py)

See the documentation for the handling of namespaces, if important in your case.

In Python 3, this is possible using (thanks to @fantastory)

exec(open(test2.py).read())

However, you should consider using a different approach; your idea (from what I can see) doesnt look very clean.

Another way:

File test1.py:

print test1.py

File service.py:

import subprocess

subprocess.call(test1.py, shell=True)

The advantage to this method is that you dont have to edit an existing Python script to put all its code into a subroutine.
