In this assignment you will revisit reading data from a file, and use that data as arguments (parameters) for a number functions you will write. You will need to: Write and test a function square_each(nums) Where nums is a (Python) list of numbers. It modifies the list nums by squaring each entry and replacing its original value. You must modify the parameter, return will not be allowed! Write and test a function sum_list(nums) Where nums is a (Python) list of numbers. It returns the sum of the numbers in passed-in the list. Write and test a function to_numbers(str_list) Where str_list is a list of strings, each of which represents a number. Modify each entry in the list by converting it to a number. You can choose to use return the list, or just modify str_list in-place, similar to
