Python List: Exercise - 246 with Solution

Write a Python program to check if a given function returns True for at least one element in the list.

Use any() in combination with map() to check if fn returns True for any element in the list.

Sample Solution:

Python Code:

def some(lst, fn = lambda x: x):
  return any(map(fn, lst))

print(some([5, 10, 20, 10], lambda x: x < 2 ))

Sample Output:

True
False
