python - NameError: name 'word' is not defined -

I am trying to create a mix of word function and I'm getting an error nameError: name 'word '

  def mix word (word): characterList = list (word); Printed character list import random; Random.shuffle (characterList); Print Character List; ShuffledWord = ''. Include (character list); Print shufflewd;   
 
 traceback (most recent call final):  
 In file "", line 1, in  
 mix word (word)  
 Name error: Name 'word' is not defined    
 
 
 I think the problem is that you are calling  mix word (word)  without defining any  word  variable.
