## 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 : Example - 2 : Example - 3 : 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
```
