1Write a program with a function repeat string, which takes two arguments, an integer m and a string st. The function returns st, repeated a number of times equal to m. Print the result in the main program. 2] write a function whose two arguments are two lists of numbers. The function returns the sum of all the numbers in the two lists Note: You are not allowed to use the Python function sum, use a for loop instead to add up the list elements Test the function in the main program with these lists for arguments: [2, 3, 4] and [20, 30, 40, 50]
