Python - Assignment Operators

In this tutorial we will learn about Assignment operators in Python.

We use the assignment operator to assign any value or result of an expression to a variable.

In the following Python code we are assigning integer value 10 to the variable x.

x = 10

In the following Python code we are assigning the result of an expression to a variable

y = 10 + 20

Shorthand Assignment Operators

Lets say, we have an integer variable x which is initially set to 10. Then we increase the value by 5 and assign the new value to it.

# declare and set value
x = 10

# increase the value by 5 and re-assign
x = x + 5

Another way of writing the code x = x + 5 is by using the shorthand assignment += as shown below.

# declare and set value
x = 10

# increase the value by 5 and re-assign
x += 5

Following is the list of shorthand assignment operators.

Example

Write Python program to add the value of two variables x and y having value 10 and 20 respectively and print the sum.

# variable
x = 10
y = 20

print("Result:", (x + y))

We can achieve the same result by adding the value of y to x and saving the result in x.

# variable
x = 10
y = 20

# result
x += y

print("Result:", x)
