classmethod date. today ¶ Return the current local date. This is equivalent to date.fromtimestamp(time.time()). classmethod date. fromtimestamp (timestamp) ¶ Return the local date corresponding to the POSIX timestamp, such as is returned by time.time().
When date.today() is called a known date is returned, but calls to the date(...) constructor still return normal dates. Without this you can find yourself having to calculate an expected result using exactly the same algorithm as the code under test, which is a classic testing anti-pattern.
The modules described in this chapter provide a variety of specialized data types such as dates and times, fixed-type arrays, heap queues, double-ended queues, and enumerations. Python also provides some built-in data types, in particular, dict, list, set and frozenset, and tuple.
>>> import time >>> from datetime import date >>> today = date. today >>> today datetime.date(2007, 12, 5) >>> today == date. fromtimestamp (time. time ()) True >>> my_birthday = date (today. year, 6, 24) >>> if my_birthday < today:...
The sqlite3 module has two default adapters for Python’s built-in datetime.date and datetime.datetime types. Now let’s suppose we want to store datetime.datetime objects not in ISO representation, but as a Unix timestamp.
>>> # dates are easily constructed and formatted >>> from datetime import date >>> now = date. today >>> now datetime.date(2003, 12, 2) >>> now. strftime ("%m-%d-%y.
The sched module defines a class which implements a general purpose event scheduler: class sched. scheduler (timefunc=time.monotonic, delayfunc=time.sleep) ¶. The scheduler class defines a generic interface to scheduling events.
For example, datetime.date has two methods for returning the weekday: weekday() and isoweekday(). The difference is that one of them counts from 0-6 and the other from 1-7. Rather than keep track of that ourselves we can add a method to the Weekday enum to extract the day from the date instance and return the matching enum member:
Compare the files in the two directories dir1 and dir2 whose names are given by common. Returns three lists of file names: match, mismatch, errors. match contains the list of files that match, mismatch contains the names of those that don’t, and errors lists the names of files which could not be compared.
email.utils. parsedate (date) ¶ Attempts to parse a date according to the rules in RFC 2822. however, some mailers don’t follow that format as specified, so parsedate() tries to guess correctly in such cases. date is a string containing an RFC 2822 date, such as "Mon, 20 Nov 1995 19:12:08-0500".
