Write a function vowel_reverser that takes a word (a string) and reverses the vowels. vowels = "aeiouAEIOU" "Hello" becomes "Holle" "butterscotch" becomes "botterscutch". The e didn't switch places with anything. If the word contains anything other than letters [A..Za z] return the empty string. Punctuation, special symbols, hypthens, spaces etc should return the empty string. In [48]: from string import ascii_letters In [55]: #ascii_Letters is uppercase + Lowercase combined from string import ascii_letters vowels = "aeiouAEIOU" def vowel_reverser (word): output = "" for i in word: if i == vowels: else: return(output) In [56]: vowel_reverser("Hello")
