Question & Answer :
This is my codification:
import datetime present = datetime.day.present() mark(present)
This prints: 2008-eleven-22 which is precisely what I privation.
However, I person a database I’m appending this to and past abruptly all the things goes “wonky”. Present is the codification:
import datetime mylist = [datetime.day.present()] mark(mylist)
This prints [datetime.day(2008, eleven, 22)]. However tin I acquire conscionable a elemental day similar 2008-eleven-22?
The Wherefore: dates are objects -——————————-
Successful Python, dates are objects. So, once you manipulate them, you manipulate objects, not strings oregon timestamps.
Immoderate entity successful Python has 2 drawstring representations:
- The daily cooperation that is utilized by mark tin beryllium acquire utilizing the str() relation. It is about of the clip the about communal quality readable format and is utilized to easiness show. Truthful str(datetime.datetime(2008, eleven, 22, 19, fifty three, forty two)) offers you '2008-eleven-22 19:fifty three:forty two'.
- The alternate cooperation that is utilized to correspond the entity quality (arsenic a information). It tin beryllium acquire utilizing the repr() relation and is useful to cognize what benignant of information your manipulating piece you are processing oregon debugging. repr(datetime.datetime(2008, eleven, 22, 19, fifty three, forty two)) offers you 'datetime.datetime(2008, eleven, 22, 19, fifty three, forty two)'.
What occurred is that once you person printed the day utilizing mark, it utilized str() truthful you may seat a good day drawstring. However once you person printed mylist, you person printed a database of objects and Python tried to correspond the fit of information, utilizing repr().
The However: what bash you privation to bash with that? -——————————————————
Fine, once you manipulate dates, support utilizing the day objects each agelong the manner. They received 1000 of utile strategies and about of the Python API anticipate dates to beryllium objects.
Once you privation to show them, conscionable usage str(). Successful Python, the bully pattern is to explicitly formed every part. Truthful conscionable once it’s clip to mark, acquire a drawstring cooperation of your day utilizing str(day).
1 past happening. Once you tried to mark the dates, you printed mylist. If you privation to mark a day, you essential mark the day objects, not their instrumentality (the database).
E.G, you privation to mark each the day successful a database :
for day successful mylist : mark str(day)
Line that successful that circumstantial lawsuit, you tin equal omit str() due to the fact that mark volition usage it for you. However it ought to not go a wont :-)
Applicable lawsuit, utilizing your codification -———————————————-
import datetime mylist = [] present = datetime.day.present() mylist.append(present) mark mylist[zero] # mark the day entity, not the instrumentality ;-) 2008-eleven-22 # It's amended to ever usage str() due to the fact that : mark "This is a fresh time : ", mylist[zero] # volition activity >>> This is a fresh time : 2008-eleven-22 mark "This is a fresh time : " + mylist[zero] # volition clang >>> can not concatenate 'str' and 'datetime.day' objects mark "This is a fresh time : " + str(mylist[zero]) >>> This is a fresh time : 2008-eleven-22
Precocious day formatting -————————
Dates person a default cooperation, however you whitethorn privation to mark them successful a circumstantial format. Successful that lawsuit, you tin acquire a customized drawstring cooperation utilizing the strftime() methodology.
strftime() expects a drawstring form explaining however you privation to format your day.
E.G :
mark present.strftime('We are the %d, %b %Y') >>> 'We are the 22, Nov 2008'
Each the missive last a "%" correspond a format for thing:
- %d is the time figure (2 digits, prefixed with starring zero’s if essential)
- %m is the period figure (2 digits, prefixed with starring zero’s if essential)
- %b is the period abbreviation (three letters)
- %B is the period sanction successful afloat (letters)
- %y is the twelvemonth figure abbreviated (past 2 digits)
- %Y is the twelvemonth figure afloat (four digits)
and many others.
Person a expression astatine the authoritative documentation, oregon McCutchen’s speedy mention you tin’t cognize them each.
Since PEP3101, all entity tin person its ain format utilized mechanically by the methodology format of immoderate drawstring. Successful the lawsuit of the datetime, the format is the aforesaid utilized successful strftime. Truthful you tin bash the aforesaid arsenic supra similar this:
mark "We are the {:%d, %b %Y}".format(present) >>> 'We are the 22, Nov 2008'
The vantage of this signifier is that you tin besides person another objects astatine the aforesaid clip.
With the instauration of Formatted drawstring literals (since Python three.6, 2016-12-23) this tin beryllium written arsenic
import datetime f"{datetime.datetime.present():%Y-%m-%d}" >>> '2017-06-15'
Localization -———–
Dates tin mechanically accommodate to the section communication and civilization if you usage them the correct manner, however it’s a spot complex. Possibly for different motion connected Truthful(Stack Overflow) ;-)
