Write a PYTHON code with at least 2 functions (one should call the other). The function which is called by the first function should also be able to be called directly. Execute these functions with various parameters such that you can demonstrate the following: Each function should have some debug code so you can trace calls to the functions and activity within the functions. Each should handle at least 2 types of exceptions (both shouldn't handle the same exceptions). The function called by the first one should, at some point, generate a division by zero error, but should NOT handle this error. The function that calls the division by zero function should handle a division by zero error. Catch one error and raise a different one. Have some finally code (perhaps with some debugging output) Demonstrate & explain: call the division by zero function both from your main program and from the other function. show that the exception isn't handled by the function itself but by the other…
