time modular1： summary
Classification of time representation
Time stamp
Formatted time string
Structured time
Time stamp ： The time stamp indicates that the 1970 year 1 month 1 The whole day 0 The offset from the point to the current second , The data type is floating point , Mainly used to let the computer see
Formatted time string ： Such as 2019-01-26 etc. , The data type is string , Mainly for people
Structured time ： Structured time groups time , Such as in , month , Japan , when , branch , Seconds, etc , Data type is a ancestor , Mainly do time conversion
Import related libraries
import time1. Time stamp 1.1 time.time()time.time() What you can get is Time stamp . namely 1970 year 1 month 1 Japan 0 when 0 branch 0 The offset from seconds to the present time s
t1 = time.time()print('t1：', t1)
Convert timestamps to A fixed format String , have access to time.ctime() Method .（ But not very often ）
t = time.ctime(time.time())print(t)
It is easier for us to use structured time
2.1 Local timeLocal time is related to time zone .
t2 = time.localtime(time.time()) print("t2:", t2)
Greenwich mean time (0 The time zone ) Later than Beijing time 8 Hour only ( Global benchmarks , Using this time can eliminate the impact of writing code in different places )
t3 = time.gmtime(time.time())print("t3：", t3)
String form is generally accepted by human beings
t4 = time.strftime("%Y/%m/%d %H:%M:%S", t2)print(t4)print(type(t4))
Reverse operation of the above operation
t5 = time.strptime('2022/06/22 20:30:35', "%Y/%m/%d %H:%M:%S")print(t5)
print(" year ：", t2.tm_year)print(" month ：", t2.tm_mon)print(" Japan ：", t2.tm_mday)print(" when ", t2.tm_hour)print(" branch ", t2.tm_min)print(" second ", t2.tm_sec)print(" Days of the week have passed ：", t2.tm_wday)print(" This year has passed ：", t2.tm_yday)print(" Is it daylight saving time ", t2.tm_isdst)
t7 = time.mktime(t2)print(t7)
