Python Question

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

I have a script named test1.py which is not in a module. It just has code that should execute when the script itself is run. There are no functions, classes, methods etc. I have another script which runs as a service. I want to call test1.py from the script running as a service.

eg:

test1.py

print "I am a test"
print "see! I do nothing productive."


service.py

# lots of stuff here
test1.py # do whatever is in test1.py


I'm aware of one method which is opening the file, reading the contents, and basically eval'ing it. I'm assuming there's a better way of doing this. Or at least I hope so.

Answer

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()
