list() and set() require iterables. They won't work with single values:

>>> set(4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>> set((1,))
{1}
>>> list(3)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
>>> list([3])
[3]
>>> list((3,))
[3]

The error you are getting is not from max() its from list()/set()

What is slightly annoying is that, unlike max(), you cannot
just pass a sequence of values:

>>> set(1,2)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: set expected at most 1 argument, got 2
