Python Numbers & Types Tutorial with Example

Python numbers are a data type that stores numeric values. It’s an immutable data type – means that it can change the value of the data variable in a new value allocated. In this tutorial, you will learn about Python number data types with examples.

Python Numbers Simple example 

Here directly showing the number and using a variable. Printing a value and type in the console. In output showing its type is class – <class ‘int’>

number = 14

print(1234567890)
print(type(number))

Output: 1234567890
<class ‘int’>

Python Numbers Types

Python supports integers, floating point numbers and complex numbers. They are defined  as :

•  int,
•  float
• and complex class in Python.

Int Type

A whole number (Int or integer ),  + positive or – negative, without decimals of no limit length.

number = 14
long_no = 3523434362343534343
negative_no = -3255522

print(type(number))
print(long_no)
print(negative_no)

Output : <class ‘int’>
3523434362343534343
-3255522

Float Type

A Float or floating-point number is a number that can positive or negative and containing one or more decimals. Float numbers can also be scientific numbers with an “e” to indicate the power of 10.

no1 = 18.10
no2 = 1.0
no3 = -35.59

print(type(no1))
print(no2)
print(no3)

Output : <class ‘float’>
1.0
-35.59

Complex Type (Imaginary numbers)

Complex numbers are written with a “j” as the imaginary part. In python, you can put ‘j’ or ‘J’ after a number to make it imaginary, so you can write complex literals easily:

x = 7+5j
print(type(x))
print(x)

Output : <class ‘complex’>
(7+5j)
