A lot of languages have more than one way to loop and python is no exception. For in is the other main loop in python. Below is a example of how for in works –

names= ["bert", "fred", "sally"]
for x in names:
    print x

It is a simpler way of iterating over a list or array. It can also be used on strings –

text = "hello"
for x in text:
    print x

The text or list comes after the in keyword. Every time it loops it will perform the following operation –

x = array[current_position]

The equivalent while loop would look something like this –

names= ["bert", "fred", "sally"]
current_position = 0
while current_position < len(names):
     x = names[current_position]
     print x
     current_position = current_position + 1

Write a for in loop to print off the following array.

subjects = ["ICT", "maths", "PE", "RE"]
