确定给定时间是否介于开始时间和结束时间之间

import datetime

    start_time = datetime.datetime.strptime(start_time, "%Y-%m-%dT%H:%M:%S")
    end_time = datetime.datetime.strptime(end_time, "%Y-%m-%dT%H:%M:%S")
    given_time = datetime.datetime.strptime(given_time, "%Y-%m-%dT%H:%M:%S")
    
    if start_time <= given_time <= end_time:
        return True
    else:
        return False

start_time = "2022-01-01T00:00:00"
end_time = "2022-12-31T23:59:59"
given_time = "2022-06-30T12:00:00"

result = is_between(start_time, end_time, given_time)
print(result)  # 输出 True
