Python: Takes two lists and returns True if they have at least one common member

Python List: Exercise-11 with Solution

Write a Python function that takes two lists and returns True if they have at least one common member.

Example - 1 :

Python: Takes two lists and returns True if they have at least one common member

Example - 2 :

Python: Takes two lists and returns True if they have at least one common member

Example - 3 :

Python: Takes two lists and returns True if they have at least one common member

Sample Solution-1:

Python Code:

def common_data(list1, list2):
     result = False
     for x in list1:
         for y in list2:
             if x == y:
                 result = True
                 return result
print(common_data([1,2,3,4,5], [5,6,7,8,9]))
print(common_data([1,2,3,4,5], [6,7,8,9]))

Sample Output:

True                                                                                                          
None

Sample Solution-2:

  • Check if any value in lsts is contained in nums using a for loop.
  • Return True if any one value is found, False otherwise.

Python Code:

def test_includes_any(nums, lsts):
    for x in lsts:
        if x in nums:
            return True
    return False    
print(test_includes_any([10, 20, 30, 40, 50, 60], [22, 42]))
print(test_includes_any([10, 20, 30, 40, 50, 60], [20, 80]))

Sample Output:

False
True
