Python: Remove all strings from a given list of tuples

Python List: Exercise - 192 with Solution

Write a Python program to remove all strings from a given list of tuples.

Sample Solution:

Python Code:

def test(list1):
    result =   [tuple(v for v in i if not isinstance(v, str)) for i in list1]
    return list(result)

marks = [(100, 'Math'), (80, 'Math'), (90, 'Math'), (88, 'Science', 89), (90, 'Science', 92)]
print("\nOriginal list:")
print(marks)
print("\nRemove all strings from the said list of tuples:")
print(test(marks))

Sample Output:

Original list:
[(100, 'Math'), (80, 'Math'), (90, 'Math'), (88, 'Science', 89), (90, 'Science', 92)]

Remove all strings from the said list of tuples:
[(100,), (80,), (90,), (88, 89), (90, 92)]
