Why One Might Trace a Function. Tracing is simulating the execution of a program, to step through the program line-by-line, showing how the variables change. Experienced programmers use tracing to debug programs, often as a substitute for a debugger. Tracing is also great for beginners who are learning a language. “Cheers, love! The cavalry’s here!” — Tracer. …

To filter the calls that will be traced, you can return a predicate function from the code_filter () method of your Config (). This function should take a Python code object and return a boolean: True means the function will be traced, and False means it will not. The DefaultConfig includes a default code filter.
Tracing a Program As It Runs - Python Module of the Week

The trace hook is modified by passing a callback function to sys.settrace (). The callback will receive three arguments, frame (the stack frame from the code being run), event (a string naming the type of notification), and arg (an event-specific value). There are 7 event types for different levels of information that occur as a program is being executed.
