Profiling subprocess Popen calls in Python

Question

I have a programm that calls several external scripts by using popen from subprocess. Now I want to profile this programm. While I can easily profile the python code with cProfile I get no information on how long the different external scripts run.

I want to avoid messuring every single popen call with a timer.

Thank you!

Answer 1

As Simeon said, you just need to write the timing code once. A way to do it would be to decorate the popen function.
