Syntax error Remove matching tuples in Python

Remove matching tuples in Python



When it is required to remove the matching tuples from two list of tuples, the list comprehension can be used.

A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).

A list of tuple basically contains tuples enclosed in a list.

The list comprehension is a shorthand to iterate through the list and perform operations on it.

Below is a demonstration for the same −

Example

Live Demo

my_list_1 = [('Hi', 'there'), ('Jane', 'Hi'), ('how', 'are'), ('you', '!')]
my_list_2 = [('Hi', 'there'), ('Hi', 'Jane')]

print("The first list is : ")
print(my_list_1)
print("The second list is : ")
print(my_list_2)

my_result = [sub for sub in my_list_1 if sub not in my_list_2]

print("The filtered out list of tuples is : ")
print(my_result)

Output

The first list is :
[('Hi', 'there'), ('Jane', 'Hi'), ('how', 'are'), ('you', '!')]
The second list is :
[('Hi', 'there'), ('Hi', 'Jane')]
The filtered out list of tuples is :
[('Jane', 'Hi'), ('how', 'are'), ('you', '!')]

Explanation

  • Two list of tuples are defined, and are displayed on the console.
  • A list comprehension is used to iterate through the tuples.
  • This will filter out tuples that are present in both the list of tuples.
  • The ones left out are displayed on the console.
