please show me step by step in python

Task 3 - Create a global variable called num_executions, set to 0 - Every time c_to_f or emphasise is executed, num_executions should be increased by 1 - After each function has been run, print out the value of num executions Task 4 - Create a function called main. This function takes no arguments, and doesn't return anything. Move all executions of c_to f and emphasise, and the print statement from Task 3 , into the main function. Don't move the function definitions!! - Add an if block which checks if your file is being run as the main module, or whether it is being imported. If it is the main module, print a message like "This is the main module", and then run the main function. Otherwise, print a message like "This module has been imported" (see the Two ways to call a main0 function section of this week's lecture notes) - Create a second Python file. This file should not be submitted, you will just use it for testing - Inside the second file, import the first file, as though it were a module (see the Ways to Import Module section of this week's lecture notes). Ensure that "This module has been imported" is printed, as per the second step of this task
