Tracing a multiplication table w/ Python trace()

[NationalRex22]

I'm interested in understanding how to implement Python's trace module to follow the execution of a multiplication table and print its annotated results.

I researched Python documentation and internet sources related to trace() and the multiplication program to figure out how use the trace module, but I came up empty-handed.

import sys
import trace

tracer = trace.Trace(
    ignoredirs=[sys.prefix, sys.exec_prefix],
    trace=0,
    count=1)

def print_multiples(n, high):
    for i in range(1, high+1):
        print(n * i, end="   ")
    print()

def print_mult_table(high):
    """ Return a multiplication table with n rows and columns."""
    for i in range(1, high+1):
        print_multiples(i, high)

print_mult_table(7)

r = tracer.results()
r.write_results(show_missing=True, coverdir=".")

The program outputs a multiplication table, so there are no error messages. I'm using Win 8.1, Python version 3.7.3 (64-bit), and an Intel core i7-based system.

Any assistance on how the integrate the trace module with the multiplication table is appreciated.
