Python gets the system time (detailed explanation of time function)

import time

print time.time()

The output result is:

1279578704.6725271

But this is a series of numbers that is not the result we want. We can use the time module's formatting method to process it:

time.localtime(time.time())

Use the time.localtime() method, which formats the timestamp as local time.

The output result is:

time.struct_time(tm_year=2010, tm_mon=7, tm_mday=19, tm_hour=22,

tm_min=33, tm_sec=39, tm_wday=0, tm_yday=200, tm_isdst=0 )

Now it looks more promising to format it to the time we want.

time.strftime('%Y-%m-%d',time.localtime(time.time()))

Finally, use the time.strftime() method to format the large string of information just now into what we want The current result is:

2010-07-19

Time and date formatting symbols in Python:

%y represents a two-digit year (00-99)

%Y represents a four-digit year (000-9999)

%m month (01-12)

%d day in the month (0-31)

%H 24-hour hour (0-23)

%I 12-hour Hours (01-12)

%M Minutes (00=59)

%S Seconds (00-59)

%a Local simplified week name

%A Local full week name

% b Local simplified month name

%B Local complete month name

%c Local corresponding date representation and time representation

%j Day in the year (001-366)

%p Local equivalent of A.M. or P.M. Symbol

%U The number of weeks in a year (00-53) Sunday is the beginning of the week

%w The week (0-6), Sunday is the beginning of the week

%W The number of weeks in the year (00- 53) Monday is the beginning of the week

%x The corresponding local date representation

%X The corresponding local time representation

%Z The name of the current time zone

%% The % number itself
