如何在pandas (python) date列中将00:00 (HH:MM)时间转换为24:00？

import pandas as pd

# 创建一个示例DataFrame
df = pd.DataFrame({'date': ['2022-01-01', '2022-01-02'],
                   'time': ['00:00', '12:34']})

# 将date列和time列合并为datetime列
df['datetime'] = pd.to_datetime(df['date'] + ' ' + df['time'])

# 将时间格式化为24小时制的字符串
df['time_24h'] = df['datetime'].dt.strftime('%H:%M')

# 输出结果
print(df)

         date   time            datetime time_24h
0  2022-01-01  00:00 2022-01-01 00:00:00    00:00
1  2022-01-02  12:34 2022-01-02 12:34:00    12:34
