In the previous chapter, you have learned what is Python, its features, how to install Python,
programming in Python and variable.
In this chapter, you will learn about data types, comments, operators and its precedence.
Data Types
Data types are used to define the type of value a data can contain. Each variable in Python is associated
with some data type. Each data type requires a different amount of memory and has some specific
operations performed on it. Data types are divided into four categories as shown below:
Data Types
Numbers Sets Sequence Boolean
Integer/long Float String Lists
Complex Tuple
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.
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.
