Just go through each letter of word checking for its existence in 
dict2.  Return False if one misses, and True if you get through the 
whole word:

def ...():
   for c in word:
     if c not in dict2:
       return False #if any character is not in dict
   return True      # otherwise

If you know of generator expressions, and remember that True and False 
are 1 and 0 respectively, then this works

def ...():
     return sum(c in dict2   for c in word) == len(word)
