# How to get Subtraction of tuples in Python

PythonServer Side ProgrammingProgramming

When it is required to subtract the tuples, the 'map' method and lambda function can be used.

The map function applies a given function/operation to every item in an iterable (such as list, tuple). It returns a list as the result.

Anonymous function is a function which is defined without a name. In general, functions in Python are defined using 'def' keyword, but anonymous function is defined with the help of 'lambda' keyword. It takes a single expression, but can take any number of arguments. It uses the expression and returns the result of it.

Below is a demonstration of the same −

## Example

Live Demo

my_tuple_1 = (7, 8, 11, 0 ,3, 4)
my_tuple_2 = (3, 2, 22, 45, 12, 9)

print ("The first tuple is : " )
print(my_tuple_1)
print ("The second tuple is : " )
print(my_tuple_2)

my_result = tuple(map(lambda i, j: i - j, my_tuple_1, my_tuple_2))

print("The tuple after subtraction is : " )
print(my_result)

## Output

The first tuple is :
(7, 8, 11, 0, 3, 4)
The second tuple is :
(3, 2, 22, 45, 12, 9)
The tuple after subtraction is :
(4, 6, -11, -45, -9, -5)

## Explanation

• Two tuples are defined, and are displayed on the console.
• The lambda function is used to subtract each of the corresponding elements from the two tuples.
• This operation is mapped to all elements using the 'map' method.
• This result is converted into a tuple.
• This result is assigned to a value.
• It is displayed as output on the console.
