How can I make a python wrapper script that would measure the execution time of another script or another .py file using time?

You can use the timer module

from timeit import default_timer as timer
start = timer()
function_you_want_to_time()
# or import your script here
# import script_to_time
end = timer()
elapsed = str(end - start)
print(f'Run time in seconds: {elapsed}')

    I actually need to time the whole script not the function inside of the script. Example I have a benchrun.py , I need to get its execution time using wrapper.py – Hanna Escalante Aug 04 '20 at 03:35
  • It still works, just replace `function_you_want_to_time()` with `import benchrun` – Viragos Aug 07 '20 at 23:49

I had a similar problem to solve recently, my solution was to write an importable module that I could call via import MyModule that would capture script execution times along with any runtime exceptions and then push the results to a data warehouse.

My solution looked like this

import MyModule

def main():
    print("do work")

if __main__ == '__main__':
    try:
        main()
    except Exception as e:
        MyModule.script.script_execution(e)
    else:
        MyModule.script.script_execution()

The MyModule would like something like this

MyModule.__init__.py

from datetime import datetime


class ScriptExeuction:
    def __init__(self):
        self.start_time = datetime.now()

    def script_execution(self, exception=None):
        self.end_time = datetime.now()
        print(f"Execution took {self.end_time - self.start_time}")


if __name__ == '__main__':
    pass
else:
    script = ScriptExeuction()

Naturally you would need to extend this to put the data where you want it, but you can easily extend the ScriptExecution class to handle the logic of pushing your data somewhere and you can capture the exceptions that occur in the script.
