如何在Python中计算一个组内的datetime之间的差异？

from datetime import datetime, timedelta

def calculate_datetime_difference(datetimes):
    differences = []
    for i in range(len(datetimes) - 1):
        difference = datetimes[i+1] - datetimes[i]
        differences.append(difference)
    return differences

# 示例数据
datetimes = [
    datetime(2022, 1, 1, 12, 0, 0),
    datetime(2022, 1, 1, 12, 15, 0),
    datetime(2022, 1, 1, 12, 30, 0),
    datetime(2022, 1, 1, 13, 0, 0)
]

differences = calculate_datetime_difference(datetimes)
for difference in differences:
    print(difference)
