Given Tuple list, filter tuples which are having just int data type.
Input : [(4, 5, “GFg”), (3, ), (“Gfg”, )]
Output : [(3, )]
Explanation : 1 tuple (3, ) with all integral values.Input : [(4, 5, “GFg”), (3, “Best” ), (“Gfg”, )]
Output : []
Explanation : No tuple with all integers.
Method #1 : Using loop + isinstance()
In this, we iterate the each tuple and check for data type other than int, using isinstance(), if found tuple is flagged off and omitted.
Python3
# Python3 code to demonstrate working of # Filter Tuples with Integers# Using loop + isinstance() # initializing listtest_list = [(4, 5, "GFg"), (5, 6), (3, ), ("Gfg", )] # printing original listprint("The original list is : " + str(test_list)) res_list = []for sub in test_list: res = True for ele in sub: # checking for non-int. if not isinstance(ele, int): res = False break if res : res_list.append(sub) # printing resultsprint("Filtered tuples : " + str(res_list)) |
The original list is : [(4, 5, 'GFg'), (5, 6), (3, ), ('Gfg', )]
Filtered tuples : [(5, 6), (3, )]
Method #2 : Using all() + list comprehension + isinstance()
In this, all() is used to check if all elements are integers using isinstance(), if that checks, tuples are added to result.

The original list is : [(4, 5, 'GFg'), (5, 6), (3, ), ('Gfg', )]
Filtered tuples : [(5, 6), (3, )]
