Python获取数据，根据连续的时间点，识别出时间段

如果原数据是字符串
只想到遍历，用datetime 转换成时间，计算输出

import datetime
data = '''2022-03-01 00:00:00 20
2022-03-01 00:05:00 20
2022-03-01 00:10:00 20
2022-03-01 00:15:00 20
2022-03-01 00:25:00 20
2022-03-01 00:26:00 20
2022-03-01 00:27:00 20
2022-03-01 00:35:00 20
2022-03-01 00:40:00 20
2022-03-01 00:42:00 20
2022-03-01 00:55:00 20
2022-03-01 01:00:00 20
2022-03-01 01:06:00 20'''

data_list = data.split("\n")

st = ""
en = ""
t1 = 0
cnt = 1
for d in data_list:
    if st == "":
        # print("初始化")
        st = d
        t1 = datetime.datetime.strptime(d[:19], '%Y-%m-%d %H:%M:%S')
        continue
    t2 = datetime.datetime.strptime(d[:19], '%Y-%m-%d %H:%M:%S')
    # print(d ,'\t',(t2 - t1).total_seconds())
    if (t2 - t1).total_seconds() <600:
        t1 = t2
        en = d
    else:
        print("时间段{},开始{},结束{}".format(cnt,st,en))
        st = d
        t1 = t2
        cnt = cnt + 1
        en = ""

if en !="":
    print("时间段{},开始{},结束{}".format(cnt, st, en))
