替換python中的列表元素

Question

該函數應返回文本與字替換爲星號。 不知道爲什麼我的原始代碼不會工作，因爲邏輯似乎對我來說是正確的。

text = "this shit is cool" 
def censor(text, word): 
    lst = text.split() 
    ast = "" 
    result = '' 
    for char in word: 
     ast += "*" 
    for wrd in lst: 
     if wrd == word: 
      wrd = ast #why doesn't this part work?? 

    print " ".join(lst) 

censor(text, "shit") 

這是我查找了一些其他相關問題後更正的代碼。它似乎更復雜和不必要。爲什麼這個工作而不是我的原始代碼？

def censor(text, word): 
    lst = text.split() 
    ast = "" 
    result = '' 
    for char in word: 
     ast += "*" 
    for wrd in lst: 
     if wrd == word: 
      loc = lst.index(word)  #I can't just change it directly? using wrd? 
      lst[loc] = ast 

    return " ".join(lst)

試試這個：

def censor(text,word): 
    return text.replace(word,'*'*(len(word)))
