The learning module carrying # Time
#time module: 1, the time stamp; meaning is convenient for doing operation; 2, the structure of the time; 3, string time
Import Time
# # timestamp
represents # print (time.time ()) # at 0:00 on January 1, 1970 00:00 Shi now with the number of seconds in 1970 was the birth of time liunx
## structured time ---- Local time
# print (time.localtime ()) # results obtained : a time.struct_time (tm_year = 2019, 10 = tm_mon, tm_mday =. 3, tm_hour =. 17, tm_min =. 7, 44 is tm_sec =, = tm_wday. 3, tm_yday = 276, the tm_isdst = 0)

# Print (t.tm_year)
# Print (t.tm_mon)

# # structure of time - --utc
# Print (time.gmtime ()) # structured save time difference method of the above 8 hours
# string time: Attractive convenience, I see a format is usually
## to convert into a structured time stamp
# Print (time.mktime (time.localtime ()))

# # structured time to convert string time

time module
time module performance in time there are three main formats:
a, timestamp timestamp, the timestamp indicates the beginning from January 1, 1970 00:00:00 1st shift amount calculated in seconds
b, struct_time time tuples, a total of nine groups of elements.
c, format time format time, formatted structure makes time more readable. Comprising a fixed format and custom format.
