This module allows you to output calendars like the Unix cal program,and provides additional useful functions related to the calendar. By default,these calendars have Monday as the first day of the week, and Sunday as the last(the European convention). Use
setfirstweekday()
to set the first day ofthe week to Sunday (6) or to any other weekday. Parameters that specify datesare given as integers. For relatedfunctionality, see also the datetime
and time
modules.The functions and classes defined in this moduleuse an idealized calendar, the current Gregorian calendar extended indefinitelyin both directions. This matches the definition of the “proleptic Gregorian”calendar in Dershowitz and Reingold’s book “Calendrical Calculations”, whereit’s the base calendar for all computations. Zero and negative years areinterpreted as prescribed by the ISO 8601 standard. Year 0 is 1 BC, year -1 is2 BC, and so on.

Calendar
(firstweekday=0)¶Creates a
Calendar
object. firstweekday is an integer specifying thefirst day of the week. 0
is Monday (the default), 6
is Sunday.A
Calendar
object provides several methods that can be used forpreparing the calendar data for formatting. This class doesn’t do any formattingitself. This is the job of subclasses.I have Python 3.8 installed via Homebrew and updated that to 3.9:% brew list -formula grep python [email protected] [email protected] I want to use Python 3.8 as my default version with python3 command and tried – inspired by this answer – the following: brew unlink [email protected] brew unlink [email protected] brew link [email protected] The last gave me the following.

Calendar
instances have the following methods:iterweekdays
()¶Return an iterator for the week day numbers that will be used for oneweek. The first value from the iterator will be the same as the value ofthe
firstweekday
property.itermonthdates
(year, month)¶Return an iterator for the month month (1–12) in the year year. Thisiterator will return all days (as
datetime.date

yeardatescalendar
(year, width=3)¶Return the data for the specified year ready for formatting. The returnvalue is a list of month rows. Each month row contains up to widthmonths (defaulting to 3). Each month contains between 4 and 6 weeks andeach week contains 1–7 days. Days are
datetime.date
objects.yeardays2calendar
(year, width=3)¶Return the data for the specified year ready for formatting (similar to
yeardatescalendar()
). Entries in the week lists are tuples of daynumbers and weekday numbers. Day numbers outside this month are zero.yeardayscalendar

yeardatescalendar()
). Entries in the week lists are day numbers. Daynumbers outside this month are zero.calendar.

TextCalendar
instances have the following methods:formatmonth
(theyear, themonth, w=0, l=0)¶Return a month’s calendar in a multi-line string. If w is provided, itspecifies the width of the date columns, which are centered. If l isgiven, it specifies the number of lines that each week will use. Dependson the first weekday as specified in the constructor or set by the
setfirstweekday()
method.prmonth

formatmonth()
.formatyear

Ubuntu com 19 04. Depends onthe first weekday as specified in the constructor or set by the
setfirstweekday()
method. The earliest year for which a calendarcan be generated is platform-dependent.pryear

formatyear()
.calendar.
HTMLCalendar
(firstweekday=0)¶This class can be used to generate HTML calendars.
HTMLCalendar
instances have the following methods:formatmonth
(theyear, themonth, withyear=True)¶Return a month’s calendar as an HTML table. If withyear is true the yearwill be included in the header, otherwise just the month name will beused.
formatyear

more styles can be added for each day:
Note that the length of this list must be seven items.

¶The CSS class for the whole month’s table (used by
formatmonth()
).The default value is 'month'

formatyear()
). The default value is 'year'
.New in version 3.7.
cssclass_year_head
¶The CSS class for the table head for the whole year (used by
formatyear()
). The default value is 'year'
.Note that although the naming for the above described class attributes issingular (e.g.
cssclass_month
cssclass_noday
), one can replace thesingle CSS class with a space separated list of CSS classes, for example:Here is an example how
HTMLCalendar
can be customized:calendar.
LocaleTextCalendar
(firstweekday=0, locale=None)¶Bethesda mobile site. This subclass of
TextCalendar
can be passed a locale name in theconstructor and will return month and weekday names in the specified locale.If this locale includes an encoding all strings containing month and weekdaynames will be returned as unicode.calendar.

You make me sick, you weed!
Mr Chigger: Now look here..
Mr Anemone: All right, all right. I'll give you one more chance, get on the table..
Mr Chigger: Look, I came here to learn how to fly an aeroplane.
Mr Anemone: A what?
