我需要它帮助shell脚本，python脚本或任何可以做到这一点的东西。我想创建一个脚本，可以将以下信息从“txt”文件解析为csv。我需要解析的在线成绩簿的信息是获取用户名和实验室分数。实验室得分可以在这一行找到

Your score for this lab: 20/20

并且可以在此行找到用户名

Student: username0

Student: username0

Answer 1

呸，这在Python中很容易做到，为什么不与你分享呢？

def filtered(lines):
    for line in lines:
        if line.startswith('Student:') or line.startswith('Your score for this lab:'):
            yield line.rstrip().split()[-1]

with open('test.txt', 'r') as f:
    for student, score in zip(*[filtered(f)]*2):
        print(student, score)
