Python – Filter Tuples with Integers

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 list
test_list = [(4, 5, "GFg"), (5, 6), (3, ), ("Gfg", )]

# printing original list
print("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 results
print("Filtered tuples : " + str(res_list))

Output

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.

Python3

# Python3 code to demonstrate working of
# Filter Tuples with Integers
# Using all() + list comprehension + isinstance()

# initializing list
test_list = [(4, 5, "GFg"), (5, 6), (3, ), ("Gfg", )]

# printing original list
print("The original list is : " + str(test_list))

# list comprehension to encapsulate in 1 liner
res = [sub for sub in test_list if all(isinstance(ele, int) for ele in sub)]

# printing results
print("Filtered tuples : " + str(res))

Output

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