python - 我如何只读取文本文件每一行的第一个单词？

Question

我想知道如何只读取文本文件中每一行的第一个单词。我尝试了各种代码并尝试更改代码，但只能设法从文本文件中读取整行。我使用的代码如下所示:

QuizList = []
with open('Quizzes.txt','r') as f:
            for line in f:
                QuizList.append(line)
        line = QuizList[0]
        for word in line.split():
            print(word)

这是指尝试仅从第一行中提取第一个单词。为了对每一行重复该过程，我将执行以下操作:

QuizList = []
with open('Quizzes.txt','r') as f:
            for line in f:
                QuizList.append(line)
capacity = len(QuizList)
capacity = capacity-1
index = 0
while index!=capacity:
    line = QuizList[index]
    for word in line.split():
        print(word)
        index = index+1

Answer 1

您正在使用 split在错误的点，尝试:

for line in f:
    QuizList.append(line.split(None, 1)[0]) # add only first word
