Python | Remove particular element from tuple list
  • Last Updated : 28 Aug, 2019

Since the advent of popularity of Python in data analysis, we have list of tuples as a container in many of our problems. Sometimes, while data preprocessing, we might have a problem in which we need to completely remove a particular element from a list of tuple. Let’s discuss a way in which this task can be performed.

Method : Using list comprehension
This task can be used using brute force manner using loop, but a better alternative shorthand would be an approach which could perform this task in one line. List comprehension can help us achieve it and hence it’s recommended to use this method to perform this task. This just checks for element and removes if it’s the selected element.

# Python3 code to demonstrate working of
# Remove particular element from tuple list
# using list comprehension
  
# initialize list
test_list = [(5, 6, 7), (7, 2, 4, 6), (6, 6, 7), (6, 10, 8)]
  
# printing original list
print("The original list is : " + str(test_list))
  
# declaring remove element
N = 6
  
# Remove particular element from tuple list
# using list comprehension
res = [tuple(ele for ele in sub if ele != N) for sub in test_list]
  
# printing result
print("The Tuple List after removal of element : " + str(res))

Output :

The original list is : [(5, 6, 7), (7, 2, 4, 6), (6, 6, 7), (6, 10, 8)]
The Tuple List after removal of element : [(5, 7), (7, 2, 4), (7, ), (10, 8)]
