Check lists have same contents

Checks if two lists contain the same elements regardless of order.

Use set() on the combination of both lists to find the unique values.
Iterate over them with a for loop comparing the count() of each unique value in each list.
Return False if the counts do not match for any element, True otherwise.

def have_same_contents(a, b):
  for v in set(a + b):
    if a.count(v) != b.count(v):
      return False
  return True

have_same_contents([1, 2, 4], [2, 4, 1]) # True
