Python -将datetime对象与列表中的下一个进行比较

from datetime import datetime

def compare_datetime_with_next(lst):
    for i in range(len(lst) - 1):
        current_datetime = lst[i]
        next_datetime = lst[i+1]
        if current_datetime < next_datetime:
            print(f"{current_datetime} is before {next_datetime}")
        elif current_datetime > next_datetime:
            print(f"{current_datetime} is after {next_datetime}")
        else:
            print(f"{current_datetime} is equal to {next_datetime}")

# 示例列表
datetime_list = [
    datetime(2022, 1, 1),
    datetime(2022, 2, 1),
    datetime(2022, 3, 1),
    datetime(2022, 4, 1)
]
