Write a Python function, called counting, that takes two arguments (a string and an integer), and returns the number of digits in the string argument that are lower than the integer argument. Include a main function that inputs the two values (string and integer) and outputs the result, with appropriate labelling. You are not permitted to use the Python string methods (such as count(), etc.). Sample input/output: Please enter a string of digits: 3459835 Please enter a 1-digit value: 5 The number of digits that are lower than 5 is 3 Select all of the functions that could be called, without error, using the following code: x = Y = 5 z = 2.0 print(function1 (x, y, z) *3.5)
