# 2. Numbers in Python

There are two major types of numbers in python: **integer **(whole numbers) and **float **(decimal numbers). You can play with the two data types In a Python, as follow:

Python ignore blank spaces when dealing with numbers.
e.g. `23+54`

and `23 + 54`

are both OK.

You can also put numbers into variables (or placeholder of values), and perform operations on them.

Note that upper case and lower case matters in Python variable names (case-sensitive).
e.g.

and**Y**

are two different variables, and so are**y**

and **MyVariable****myvariable**
