I know sys.settrace() works very well if I do something like the following

def add(a,b):
    return a+b
def my_tracer():
    pass
sys.settrace(my_tracer)
add(1,2)

My question is: Can I do the same thing for a general form of code implementation? Say I have my code written into a file, or I have the full code loaded in a very long string that would normally be run by something like

exec(code_file)

Is there a way to still do something like the following?

sys.settrace(my_tracer)
exec(code_file)

If so, how can I get rid of all the redundant components and only focus on the code execution as if the code was implemented (like def add) in the first place?

Intended outcome:

sys.settrace(my_tracer)
exec(code_file)

working just like

sys.settrace(my_tracer)
add(1,2)
