Python Basics - Naming things // Sintax question

Question

I doing the Python Basics and got to the "Naming Things" video.

At 01:58 Kenneth writes down:

favourite_fruit = "apple"
favorite_number = 42

Why is it that the 42 doesnt have quote marks?

Like...................favorite_number = "42"

Sorry but english is my second language :P

The difference is the type of variable:

first_number = 42    # <-- this variable is a number
other_number = "42"  # <-- this variable is a string

The first one can be used later for math, the second one could not (without conversion).
