# Check lists have same contents

Canonical: https://www.wiki.jodisand.me/snippets/python/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.

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

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