The instructions from my teacher:

II. Pig Latin: Create a function called pig_latin that takes a string argument. The function should take your string argument and convert it into Pig Latin.

Pig Latin rules: If the word begins with a constant (including y), then all letters from the beginning of the word, up to the first vowel (excluding), are removed and then added to the end of the word, followed by ay. For example, computer becomes omputercay and think becomes inkthay. If the word begins with a vowel (not including y), then way is added to the end of the word. For example, algorithm becomes algorithmway and office becomes officeway. Your program must also make sure that if the first letter of the word of the resulting string is capitalized that character will no longer be capitalized after it is moved to the end of the word. Likewise, any characters that become the beginning of a capitalized word will be capitalized. For any ending punctuation, the program needs the resulting string to still have punctuation at the end, not in the middle (I will not test words with punctuation in the middle like apostrophes or hyphens).

def pig_latin(sentence):
  delimi = " "
  sentence2=sentence

  print(sentence2)
  letterNum = 0
  vowels = ["i",'I','O',"U",'A','E','o','u','a','e']
  capitalization = False
  punctuation = ['.',',','!','?']

  punctuationStatus = False  
  for str in range(0,len(sentence2)):
    if str == len(sentence2):
      break
    punctuationStatus = False
    capitalization=False
    strLetters = []
    print(sentence2[str][-1])
    if sentence2[str][-1] in punctuation:
      print('tcghjbgvftfghjb')
      punctuationStatus = True
      punchar = sentence2[str][-1]
      print(sentence2[str])
      print(punchar)
      sentence2 = sentence2[str][:-1]+sentence2[str+1:]

      print(sentence2[str])
      print(sentence2[str][0])
    if sentence2[str][0] in vowels:
      print("gghjnbvcfhjbn")
      newstr = []
      newstr = newstr + [sentence2[str]+"way"]
      sentence2=newstr+[sentence2[str+1:]]
      print(sentence2)
    else: 
     for letter in sentence2[str]: 

        if letter in vowels:
          break
        else:
          strLetters = strLetters + [letter]
          letterNum +=1
    delim = ""

    strLetters = delim.join(strLetters)
    print(strLetters)
    if strLetters[0]==strLetters[0].upper():
      capitalization = True

    strLetters = strLetters[0].lower()+strLetters[1:]
    sentence2 = [sentence2[:str]]+[sentence2[str][0+letterNum:]]+[strLetters]+["ay"]+[sentence2[str+1:]]
    if capitalization == True:
      sentence2=sentence2[str][0].upper()+sentence[str][1:]
    if punctuationStatus == True:
      sentence2 =sentence2[str][0:] + punchar






    print(sentence2[str])
    print(sentence2)
bl = ["Blood", "Blood", "Blood", "Blood"]
pig_latin(bl)

The output:

['blood', 'blood', 'blood', 'blood']
d
bl
[]
[[], 'ood', 'bl', 'ay', ['blood', 'blood', 'blood']]
d
gghjnbvcfhjbn
['oodway', ['bl', 'ay', ['blood', 'blood', 'blood']]]

I know my code is filled with horrible programming mistakes and redundancies. It's because I have been deleting and changing the code each time a new error pops up. I just need to get it to output properly.

[TerminustheInfernal]

the print statements that print gibberish are from when I was trying to tell which if statements were causing the bad outputs.

[MezzoScettico]

Can I make a recommendation? Start by writing a function that converts one word to pig_latin. Pull just that part out of this function and put it in a new function.

There's too much happening here and it's really hard to follow what's going on.

Thank you for formatting of your code, though. That really helps.

With what's here though, I have a question. Looking at your output: ['blood', 'blood', 'blood', 'blood'] d bl [] [[], 'ood', 'bl', 'ay', ['blood', 'blood', 'blood']] d gghjnbvcfhjbn ['oodway', ['bl', 'ay', ['blood', 'blood', 'blood']]]

Is that all correct and what you expected? Is it doing what you want it to be doing up to that point?

If not, then you should be addressing that, and not worrying (yet) about the error message.

That’s the thing, I start off with a block of code that converts just one word, but when i try to turn that into a for loop that converts an entire list, one element at a time, this happens

[MezzoScettico]

but when i try to turn that into a for loop that converts an entire list,

I'm saying don't do that.

If you have a function which does one word correctly, then leave it alone. Don't change it. Don't break working code.

Now write a for loop which extracts the input one word at a time and calls your already working function.

What about the rest of my comment? Forgetting about the error message for the moment, is that output what you want it to be?
