There are 6 main categories of data in Python. Numerics, sequences, mappings instances, exceptions and classes.
As we said above, here we'll talk about Numerics.
Numerics class itself contains three other distinct subclasses integers, floating point numbers and complex numbers.
An integer is a number doesn't have a fractional part like -5,-3,-1,0,1,2,5...etc.
A floating point number is a number has a fractional part like -3.1,-2.5,0.01,4.5 ...etc.
A complex number is a number has a real and an imaginary part like 1+I,2+5i,5-6i...etc in programming we use "j" instead of "i" .
Here are operations could be applied on all numerics.
" + " addition
" - " substation
" * " multiplication
" / " division and
" ** " raising to power.
