如何使用python打印一行特定字符串的下一个单词？

sentence = "This is a sample sentence"
word_list = sentence.split()

target_word = "sample"
index = -1
for i in range(len(word_list)):
    if word_list[i] == target_word:
        index = i
        break

if index != -1 and index < len(word_list) - 1:
    next_word = word_list[index + 1]
    print("Next word:", next_word)
else:
    print("No next word found.")
