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.
Complex
A complex is a number that is written in the form a+ bj or a+bJ. It is represented as (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 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.
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 a comma and enclosed in parentheses (). The difference
between list and tuple is that list can be modified but tuples cannot be modified after it is created.
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
