Python provides a built-in function called len that returns the length of a string, so the value of len('allen') is 5.
Write a function named right_justify that takes a string named s as a parameter and prints the string with enough leading spaces so that the last letter of the string is in column 70 of the display.
print " " + s
Its quite easy with string formatting:
def right_justify(s): print "%70s" % s
