float: It represents real number, where a fraction is denoted by a decimal point.
For example:
a = 7.5

string: A sequence of one or more characters enclosed in single or double quotes.
For example:

a = "hello"
In Python, the input() function always returns a value as a string. To use the input as a number,
you must convert it into the appropriate data type. This can be done using the following functions:

int(): Converts the input value into an integer.
For example:
a = int(input("Enter a number: "))

This code converts the user’s input into an integer before storing it in the variable a.

float(): Converts the input value into a floating-point number.
For example:
b = float(input("Enter a number: "))

This code converts the user’s input into a floating-point value before storing it in the
variable b.

COMMENTS IN PYTHON

Comments explain code for users and are ignored by Python during execution. They can be
single-line or multiline.

SINGLE-LINE COMMENT
A single-line comment is used to add brief notes or explanations to a single line of code. It starts
with the hash symbol (#).

Syntax of a single-line comment:

# This is a single-line comment

MULTILINE COMMENT

A multiline comment is used when the comment spans more than one line. Python does not have
a specific syntax for multiline comments, but you can use either consecutive single-line comments
or triple quotes (''' or """) to create a multiline comment.
By writing multiple single-line comments one after another:

# This is a multiline comment
# using single-line comment syntax
