Convert a python datetime string to a Unix Timestamp

Convert a python datetime string to a Unix Timestamp

 

Today, I encountered a problem when I used python to write a small program for capturing web pages. The time string on the page, for example, '(17:38:49)', needs to be converted

UNIX timestamp. The strtotime function was previously written in PHP and was not found in Python. The following is an example on the Internet:

Print?

1	import datetime,time

2	s = datetime.datetime(2009,1,1)

3	time.mktime(s.timetuple())

Then write the regular expression on your own and extract the number and use the above method. The leading zero can be removed using int ().

After writing it online, I accidentally found the correct solution:

Print?

1	import time,datetime

2	s = '(2011-07-01 17:38:49)'

3	s = s.lstrip('(').rstrip(')')

4	d = datetime.datetime.strptime(s,"%Y-%m-%d %H:%M:%S") # See the following table for format characters

5	print time.mktime(d.timetuple())

Time and date formatting symbols in Python:
% Y two-digit year (00-99)
% Y indicates the four-digit year (000-9999)
% M month (01-12)
One day in % d month (0-31)
% H hour in 24-hour format (0-23)
% I 12-hour (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 full month name
% C local Date and Time
% J one day in the year (001-366)
% P local equivalent of a. m. or P. M.
% U number of weeks in a year (00-53) Sunday is the start of the week
% W Week (0-6), Sunday is the beginning of the week
% W number of weeks in a year (00-53) Monday is the start of the week
% X local date Representation
% X Local Time Representation
% Z Current Time Zone name
% Itself
