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:
23+54
>> 77
​
1.3+3.5
>> 4.8
​
1/2
>> 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=4
X-3
>> 1
Note that upper case and lower case matters in Python variable names (case-sensitive).
e.g. Yandyare two different variables, and so areMyVariable and myvariable
