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:

23+54>> 771.3+3.5>> 4.81/2>> 0.5

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.

X=4X-3>> 1

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

**y**

are two different variables, and so are`MyVariable`

`myvariable`
