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 isinstance def check(x): return not isinstance (x, str ) # creating list of tuples listOfTuples = [( 'string' , 'Paras' ), ( 2 , 'Jain' ), ( 3 , 'GFG' ), ( 4 , 'Cyware' ), ( 5 , 'Noida' )] # using filter output = ([ tuple ( filter (check, x)) for x in listOfTuples]) # printing output print (output) |
Output:
[(), (2,), (3,), (4,), (5,)]
Method #2:
# Python code to remove all strings from a list of tuples # Creating list of tuples listOfTuples = [( '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 output print (output) |
Output:
[(), (2, 225), (3,), (4,), (5,)]
