Complex
A complex is a number that is written in the form a+ bj or a+bJ. It is represented as follows:
(real part) + (imaginary part) j.

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 is used to represent text-based information. The quotes are not a part of the string.
For example, "hello","Orange Education", 'Amit', '365'.

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 elements that are the same or have different data
types. For example, [1,2,5], ['HELLO',45,87.6].

Tuple
A tuple is just like a list. It contains a group of elements that can be of different data types. The
elements in the tuple are separated by commas (,) and enclosed in parentheses (). The difference
between a list and a tuple is that list can be modified but tuples cannot be modified after it is
created. For example, (7, 9.5, 3), ('a',4,3).

BOOLEAN

Boolean is a data type with two built-in values: True or False. They are used in logical evaluation.
A True statement returns value 1 while a False statement returns value 0.

FIND DATA TYPE

Python allows us to find out the type of data used in a program by using type() function.
