Answer 1

You're calling the swap/split in the wrong order. Use this instead:

w = self.swap(s.split())

Then your return shouldn't need to do any comprehension:

return ' '.join(w)

Answer 2

Another one

def revereString(orgString):
  result = []
  splittedWords = orgString.split(" ")
  for item in range(len(splittedWords)-1, -1, -1):
    result.append(splittedWords[item])
  return result

print(revereString('Hey ho hay'))

Answer 3

While there's not a whole lot wrong with wrapping it in a class, it's not exactly the most pythonic way to do things. Here's a shorter version of what you're trying to do:

def reverse(sentence):
    return ' '.join(sentence.split()[::-1])

Output:

In [29]: reverse("hello there friend")
Out[29]: 'friend there hello'
