input: Write a function called `sort_words` which takes a list of words as input and sorts them alphabetically. The function should sort the list in place and then print the sorted list. Provide assert statements with test cases to validate the function.
  assert sort_words(['bubble', 'selection', 'quicksort', 'insertion'])==['bubble', 'insertion', 'quicksort', 'selection']
  assert sort_words(['apple', 'banana', 'cherry', 'date'])==['apple', 'banana', 'cherry', 'date']
  assert sort_words(['zebra', 'kangaroo', 'elephant', 'bear'])==['bear', 'elephant', 'kangaroo', 'zebra']
  assert sort_words([])==[]
  assert sort_words(['a', 'A', 'aa', 'AA'])==['A', 'AA', 'a', 'aa']
  assert sort_words(['python', 'java', 'c', 'javascript'])==['c', 'java', 'javascript', 'python']
output: def sort_words(words):
      words.sort()
      print(words)
