Question

我能够从以下Python代码中找到序列号值。.现在要提取所有序列号（如果有多个序列号）并将其写入文本文件。是否可以实现此目的？预先感谢。

导入 FILEPATH =“ /sample.log”

def main（）：模式= re.compile（“'serial_number \'：u \'（。*？）\'”“）使用open（FILEPATH，'rU'）as f： print（'2'+ pattern.findall（f.read（））[0]）

如果名称 ==“ 主要”： main（）

import re


FILEPATH = "./file.txt"


def main():
    pattern = re.compile("'serial_number\'\: u\'(.*?)\'")
    with open(FILEPATH, 'rU') as f:
        print(pattern.findall(f.read()))


if __name__ == "__main__":
    main()
