parse string into time object and calculate the interval (in seconds)
# 计算两个时间戳的差值import timefrom datetime import datetime fmt = "%Y-%m-%dT%H:%M:%S.%fZ" #2016-02-18T12:22:22.123456Ztime1_obj = datetime.strptime(time1, fmt) time2_obj = datetime.strptime(time2, fmt) time_interval = int(time.mktime(time2_obj.timetuple()) - time.mktime(time1_obj.timetuple()))
call shell command in Python script
# Python 和 Shell 的结合在实际科研很有用 import subprocess subprocess.call(["ls", "-l"], cwd=".")
