Data types in Python

2.1. Numeric Data types (Integer, float, complex)

1.       Numeric Data Types:

Numeric data types are used to specify the number type that is stored in a variable.

Numeric data types are again categorized into three categories.

a.       Integer

b.       Float

c.       Complex

a.       Integers: this data type specifies the value that is stored in a variable is any integer number of any length.

Example: a=10, b=-20 etc.

a = 30  

print("The type of a", type(a))  

 Output:

The type of a <class ‘int’>

b.    Float: This data type specifies the value that is stored in a variable is a decimal number.

Example: 22.9, 2.7 etc

x=43.211

Print (“The type of x”, type(x))

Output:

The type of a <class ‘float’>

c.       Complex Number: This data type is used to represent numbers in the format a+bi, where a & b are real numbers and ‘I or j’ is an imaginary unit. In python complex number are created using the syntax a+bj. Operations like addition, subtraction, multiplication, and division etc can also performed on complex numbers.

 

Example

a=3+6j

print(“The type of a”, type(a))

Output:

The type of a <class ‘complex’>
