Python 在刮除.csv文件后清理该文件

几周前，我手动抓取了一个网站，测试了一些matplotlib情节，之后升级为用漂亮的汤抓取网站。我正试图像在一个旧的stackoverflow帖子中一样清理我的数据

数据组织了人们去健身房的时间，设置如下 “2020年10月27日上午9:00” “名字姓氏” “名字姓氏” “名字姓氏”

为了简化数据，我想将所有这些日期转换为对应名称的另一列

"First Name Last Name", "19:00AM on 10/27/2020"
"First Name Last Name", "19:00AM on 10/27/2020"
"First Name Last Name", "19:00AM on 10/27/2020"

以下是上次运行的代码：

import re

def is_time_format(s):
    time_re = re.compile(r'\b((1[0-2]|0?[1-9]):([0-5][0-9])([AaPp][Mm]))')
    return bool(time_re.match(s))

with open("1-weak-gym.csv") as fp:
    new_lines = []
    extra_info = ''
    for line in fp:
        last_bit = line.split(' ')[-1]
        if is_time_format(last_bit):
            extra_info = line
            continue
        else:
            new_lines.append(line.rstrip() + '\t' + extra_info)

open("newOutput", 'w').writelines(new_lines)

这是我试图清理的一些csv文件

附加在每一行名字后面的日期可能会让人困惑，但这是一个人注册使用健身房的时间，而不是实际对应的健身房时间。 这些列是，[首字母、姓名、注册日期、签署的弃权书]，现在我想在下一个注册日期发生之前的每一行添加“2020年10月26日，星期一”，上午9:00至上午9:50（50分钟），“姓名加入弃权书”。一旦我整理好数据，我就可以进入excel并删除“名称”
