def arguments():
    name=raw_input ("Please enter your firstname: ")
    surname=raw_input ("Enter your surname: ")
    address1=raw_input ("Enter Address line 1: ")
    address2=raw_input ("Enter Address line 2: ")
    address3=raw_input ("Enter Address line 3: ")
    return name,surname,address1,address2,address3
address=arguments()
print "%s %s" % address



In this case it's not actually modulus, it's just the syntax for string formatting. I'm not sure *what* the reasoning behind the % was, but that's the way it is.


There are two ways to do string formatting, the new (.format) and old (%).


In new style formatting you use the .format method of the string:


"{0} {1} {2}".format("One", 2, "Five")


You don't usually have to worry about the type, though you can specify it along with some other useful modifiers for precision, spacing, and alignment. 


In old style formatting, you use a string with format specifiers (%s, %d, etc.) followed by a tuple of arguments. Here, the lengths have to match exactly - if you have one specifier then you must have a 1-element tuple. In your case, you're returning a 5 element tuple, so you want 5 format specifiers:


print "%s %s %s %s %s" % address


However, if you just want to print the data out like that you can do it a little easier like this:


print ' '.join(address)


Or if you are in 3.x or use `from __future__ import print_function` then you can do this:


print(*address)
