Trace function calls in a Python program but ignore standard and site-packages lib calls.

my_module.py

import sys
import trace

tracer = trace.Trace(
    ignoredirs=[
        '/usr/local/lib/python3.6',  # adapt to your environment.
        '/path/to/lib/python3.6/site-packages',
    ],
    trace=1,
    count=0,
    outfile=sys.stdout
)

# Use that instead of my_function(arg_1, arg_2)
tracer.runfunc(my_function, arg_1, arg_2)

def my_function(foo, bar):
    # Do stuff
