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 

Python3

# 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:

Python3

# 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,)]

Method #3: Using type() method

Python3

# Python code to remove all strings from a list of tuples

# creating list of tuples
listOfTuples = [('string', 'Paras'), (2, 'Jain'), (3, 'GFG'),(4, 'Cyware'), (5, 'Noida')]
x=[]
for i in listOfTuples:
    p=[]
    for j in i:
        if(not (type(j) is str)):
            p.append(j)
    p=tuple(p)
    x.append(p)

# printing output
print(x)

Output

[(), (2,), (3,), (4,), (5,)]
