We can easily find out how big an array is by using the len() function. However how many bytes does it take up in memory. That is a much more difficult problem.

A string uses one byte (well 2 if it is unicode, but we will assume ascii!) per character. So the string “hello” has a size of 5 bytes. For this example we will assume that a integer is 4 bytes.

a = ["Jamie", "George", "Fred", "Sue"]
b = [4,76,24,87]

Using the above arrays AND using code work out the size, in bytes, that these two arrays take up.

Hint – You can use len(“hello”) to find out how many letters are in a string.
