# 6.48 (Format an integer) Write a function with the following header to format the integer
# with the specified width.
# def format(number, width):
# The function returns a string for the number with prefix 0s. The size of the string is
# the width. For example, format(34, 4) returns "0034" and format(34, 5)
# returns "00034". If the number is longer than the width, the function returns the
# string representation for the number. For example, format(34, 1) returns "34".
# Write a test program that prompts the user to enter a number and its width and displays
# a string returned from invoking format(number, width).
