我正在編寫一個代碼，提示用戶輸入一個句子，然后定義為str1，然后提示輸入一個定義為str2的單詞。

例如：Please enter a sentence: i like to code in python and code things

Thank you, you entered: i like to code in python and code things

Please enter a word: code

我想使用for循環在str1中查找str2，以打印是否找到該單詞，如果找到該單詞，則打印str2的索引位置。

目前我有以下代碼：str1Input = input("Please enter a sentence: ")

print("Thank you, you entered: ",str1Input)

str1 = str1Input.split()

str2 = input("Please enter a word: ")

if str2 in str1:

for str2 in str1:

print("That word was found at index position", str1.index(str2)+1)

else:

print("Sorry that word was not found")

盡管，結果似乎是打印是否找到索引位置，但隨后打印句子中每個單詞的索引位置。另外，如果我正在搜索某個在該句子中出現兩次的單詞，它只會打印該單詞在該句子中第一次出現時的索引位置，例如：Please enter a sentence: i like to code in python and code things

Please enter a word: code

Thank you, you entered: i like to code in python and code things

That word was found at index position: 1

That word was found at index position: 2

That word was found at index position: 3

That word was found at index position: 4

That word was found at index position: 5

That word was found at index position: 6

That word was found at index position: 7

That word was found at index position: 4

That word was found at index position: 9

如果有人能幫助我和其他人嘗試類似的事情，這將是非常有幫助的！
