Answer 1

我想这可能是你的意思：

word = input("Enter a word: ") 
listword = list(word) 

while True: 
    index = int(input("Enter an index: ")) 
    if index <= len(word) - 1: 
     break 
    print("Try again") 

while True: 
    letter = input("Enter a letter: ") 
    if len(letter) == 1: 
     break 

listword[index] = letter 
print("".join(listword))
