Range is a built-in function in Python that takes in the following inputs in the following order, an optional starting number, a required ending number, and an optional step size. When a starting number is not provided, range defaults to starting with 0. When a step size is not provided, range defaults to using a step size of 1. The ending number must be provided and range excludes this ending number. For example, if you want to print out each number between 0 and 3 inclusive of 0 and 3, you would do this. for i in range (4), print(i). And I'll go ahead and run this. Note that I called the range function and provided four as the input because range excludes the ending number.…
