Number

Integer numbers, floating-point numbers, and complex numbers are the built-in numeric data
types of Python.

Integer/Long: Integers are whole numbers consisting of + or – signs. They do not have
decimal places between them. The range of an integer can be from -2147483648 to
2147483647.

Float: Float data types represent numbers that contain a decimal point. For example, 0.6,
-3.257 are called floating-point numbers. These numbers can also be written using ‘e’ or ‘E’

to represent the power 10.

Sets

Set is a mutable, unordered collection of values, of any type, with no duplicate element.

Sequence

A sequence is an ordered collection of items of similar or different data types. The three types of
sequence data types are Strings, Lists and Tuples.
Strings: A string is a sequence of one or more characters put in single quotes, double quotes

or triple quotes which are used to represent text-based information. The quotes are not a
part of the string.

List: A list is a collection of data elements separated by comma(,) and enclosed within square
brackets. We can also create a list with the same or different data elements.

Boolean

Boolean is a data type with two built in values: True or False. They are used for logical evaluation.

A True statement returns value 1 while a False statement returns value 0.

COMMENTS IN PYTHON

Comments in Python can be used to explain parts of the code. It can also be used to hide the code as
well. Comments enable us to understand the way a program works. In Python, any statement starting
with # symbol is known as a comment. Python does not execute comments. Comments are not a part
of the program, but they do enhance the interactivity of the program and make it readable. Python
supports two types of comments: Single line comment and Multiline comment.
