How to profile CPython built-in methods

[ubuitrago-pjr]

Hello, my name is Uri and I am building a Container Security tool in Python. I am interested in profiling Docker containers like Flask to trace the built-in methods called by the Python interpreter at runtime. I came across Scalene and it seemed like a better fit than other profiles I have tried (py-spy, cProfile). The issue at the moment is I am unable to determine which CPython built-in methods are called during a simple Flask app's execution:

scalene --cpu-only --profile-all -n --json --outfile scalene-builtin.json -- python -m flask -A ./src/app.py run

The output is very verbose. Any tips for a beginner?
