如何在 Python 中替換短語中的字符串

Question

這是我寫的。 有人可以幫忙嗎？

def replace(phrase):
    replaced = ""
    
    for word in phrase:
        if word == ("what"):
            replaced = replaced + "the"
        else:
            replaced = replaced + word
    
    return replaced

print(replace(input("enter a phrase: ")))

Answer 1

嘗試替換方法：

def replace(phrase):
  replaced = phrase.replace("what","the")
  return replaced

Answer 2

在這里，我們使用 .split() 將您的短語按空格分開。 結果，您會得到每個單詞的列表 ['hi', 'what', 'world']。 如果你不拆分它，你將循環遍歷每個字符，如果字符串代替並且沒有字符永遠等於“什么”

 def replace(phrase):
    phrase = phrase.split()
    replaced = ""
    for word in phrase:
        if word == ("what"):
            replaced = replaced + " the "
        else:
            replaced = replaced + word
    return replaced

print(replace(input("enter a phrase: ")))

Answer 3

你可以試試這個代碼，希望對你有幫助

def replace(phrase):
    phrase = phrase.split()
    replaced = ""
    for word in phrase:
        if word == ("what"):
            replaced = replaced + " the"
        else:
            replaced = replaced +" "+ word
    return replaced[1:]

print(replace(input("enter a phrase: ")))

輸出是：

enter a phrase: where what this what when ,
where the this the when ,
