How Can I Execute One Python Script from Another, Especially When One is a Service?

Calling a Script from Another Script

Question:

How can one execute a script named "test1.py" from another script named "service.py" that is running as a service?

Answer:

To call a script from another script, the following approach is commonly employed:

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 approach consists of the following steps:

1. Define a function in test1.py: Create a function, such as "some_func()", in "test1.py" that encapsulates the code to be executed.
2. Call the function in service.py: In "service.py", import "test1.py" and call the "some_func()" function from within the "service_func()" function.
3. Entry point for each script: Ensure that the "if name == '__main__'" condition is used in both "test1.py" and "service.py" to distinguish between when the scripts are run as scripts themselves or imported by other scripts.
