1.2 Literal constant

>Literals are raw data and fixed constant values. A raw value by itself is a literal constant. They can be supplied as data to the variables.
>Literal constants in Python are numeric, string, soolean, special (None). Collection/Container of these constant types are called Literal Collections, like list/tuple. Let's see some examples.

## Numeric
a = 4
b = 6
c = 2.5
# here 4 is a integer & has no other value replacement, and is a numeric value
# so it's a numeric literal, similarly 2.5 is a decimal value and similar to
# 4, 2.5 is also a fixed value by itself as it has no replacement,
# so it is a numeric literal too


## String
a = 'something'
# same way here 'something' is a fixed value and as it is string/text value
# it is a string literal
