Python | Remove all strings from a list of tuples
Given a list of tuples, containing both integer and strings, the task is to remove all strings from list of tuples.
Examples:
Input : [(1, 'Paras'), (2, 'Jain'), (3, 'GFG'), (4, 'Cyware')]
Output : [(1), (2), (3), (4)]
Input : [('string', 'Geeks'), (2, 225), (3, '111')]
Output : [(), (2, 225), (3,)]
Method #1: Using filter() method
# Python code to remove all strings from a list of tuples # Check function to check isinstancedef check(x): return not isinstance(x, str) # creating list of tupleslistOfTuples = [('string', 'Paras'), (2, 'Jain'), (3, 'GFG'), (4, 'Cyware'), (5, 'Noida')] # using filter output = ([tuple(filter(check, x)) for x in listOfTuples]) # printing outputprint(output) |
Output:
[(), (2,), (3,), (4,), (5,)]
Method #2:
# Python code to remove all strings from a list of tuples # Creating list of tupleslistOfTuples = [('string', 'Geeks'), (2, 225), (3, '111'), (4, 'Cyware'), (5, 'Noida')] output = [tuple(j for j in i if not isinstance(j, str)) for i in listOfTuples] # printing outputprint(output) |
Output:
[(), (2, 225), (3,), (4,), (5,)]
