How Can I Execute a Standalone Python Script from Within a Service Script?

Executing External Scripts from Within a Service Script

In a scenario where you have two scripts, test1.py and service.py, with test1.py containing standalone code and service.py running as a service, you may need to call test1.py from service.py.

Implementing the Solution

The primary method for achieving this is by structuring the scripts as follows:

• test1.py:

  def some_func():
      print('in test 1, unproductive')
  
  if __name__ == '__main__':
      # test1.py executed as script
      # do something
      some_func()

  Copy after login

  In this setup, some_func() is the function you want to execute from service.py. The if __name__ == '__main__' check ensures that the code within is only executed when test1.py is run directly, not when it's imported.

• 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()

  Copy after login

  In service.py, you import test1 and define a function service_func() for your service. The critical step is calling test1.some_func(), which executes the code from test1.py. Again, the if __name__ == '__main__' check ensures the code is only executed when service.py is run directly.
