How to Add Two Numbers in Python

To add two numbers in Python, you can use the addition operator +. You can add integers, floats, and decimal variables.

a = 1
b = 2

c = a + b

print(c)

#Output:
3

One of the most fundamental operations in programming is performing different calculations and math.

You can easily add two numbers in Python with the + addition operator.

You can add integers, floats, and decimal variables in Python with +.

The rest of this article will show you examples of how you can use + to add two numbers in Python.

How to Add Two Integers in Python

The most basic use of + is if you have two integers and you want to add them together.

Below shows you a simple example of using + to add two integers in Python.

a = 1
b = 2

c = a + b

print(c)

#Output:
3

How to Add Two Floats in Python

Another type of number that you can use in Python is a floating point number. Floats allow you to create numbers which have a decimal portion.

Below shows you a simple example of using + to add two floats in Python.

a = 1.0
b = 2.0

c = a + b

print(c)

#Output:
3.0

How to Add a Float and an Integer in Python

You can add a float and an integer together with +. The result will be a float.

Below shows you how to add a float and an integer together in Python.

a = 1
b = 2.0

c = a + b

print(c)

#Output:
3.0

How to Add Two Decimals in Python

Another type of number that you can use in Python is a decimal. The decimal module provides support for fast correctly rounded decimal floating point arithmetic

Below shows you a simple example of using + to add two decimals in Python.

from decimal import *

a = Decimal('1.01')
b = Decimal('2.02')

c = a + b

print(c)

#Output:
3.03
