This module allows you to output calendars like the \UNIX{}
|
|
\program{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 \function{setfirstweekday()} to set the first day of the
|
|
week to Sunday (6) or to any other weekday.
|
|
|
|
\begin{funcdesc}{setfirstweekday}{weekday}
|
|
Sets the weekday (\code{0} is Monday, \code{6} is Sunday) to start
|
|
each week. The values \constant{MONDAY}, \constant{TUESDAY},
|
|
\constant{WEDNESDAY}, \constant{THURSDAY}, \constant{FRIDAY},
|
|
\constant{SATURDAY}, and \constant{SUNDAY} are provided for
|
|
convenience. For example, to set the first weekday to Sunday:
|
|
|
|
\begin{verbatim}
|
|
import calendar
|
|
calendar.setfirstweekday(calendar.SUNDAY)
|
|
\end{verbatim}
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{firstweekday}{}
|
|
Returns the current setting for the weekday to start each week.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{isleap}{year}
|
|
Returns true if \var{year} is a leap year.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{leapdays}{y1, y2}
|
|
Returns the number of leap years in the range
|
|
[\var{y1}\ldots\var{y2}).
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{weekday}{year, month, day}
|
|
Returns the day of the week (\code{0} is Monday) for \var{year}
|
|
(\code{1970}--\ldots), \var{month} (\code{1}--\code{12}), \var{day}
|
|
(\code{1}--\code{31}).
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{monthrange}{year, month}
|
|
Returns weekday of first day of the month and number of days in month,
|
|
for the specified \var{year} and \var{month}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{monthcalendar}{year, month}
|
|
Returns a matrix representing a month's calendar. Each row represents
|
|
a week; days outside of the month a represented by zeros.
|
|
Each week begins with Monday unless set by \function{setfirstweekday()}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{prmonth}{theyear, themonth\optional{, w\optional{, l}}}
|
|
Prints a month's calendar as returned by \function{month()}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{month}{theyear, themonth\optional{, w\optional{, l}}}
|
|
Returns a month's calendar in a multi-line string. If \var{w} is
|
|
provided, it specifies the width of the date columns, which are
|
|
centered. If \var{l} is given, it specifies the number of lines that
|
|
each week will use. Depends on the first weekday as set by
|
|
\function{setfirstweekday()}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{prcal}{year\optional{, w\optional{, l\optional{c}}}}
|
|
Prints the calendar for an entire year as returned by
|
|
\function{calendar()}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{calendar}{year\optional{, w\optional{, l\optional{c}}}}
|
|
Returns a 3-column calendar for an entire year as a multi-line string.
|
|
Optional parameters \var{w}, \var{l}, and \var{c} are for date column
|
|
width, lines per week, and number of spaces between month columns,
|
|
respectively. Depends on the first weekday as set by
|
|
\function{setfirstweekday()}.
|
|
\end{funcdesc}
|
|
|
|
\begin{funcdesc}{timegm}{tuple}
|
|
An unrelated but handy function that takes a time tuple such as
|
|
returned by the \function{gmtime()} function in the \refmodule{time}
|
|
module, and returns the corresponding Unix timestamp value, assuming
|
|
an epoch of 1970, and the POSIX encoding. In fact,
|
|
\function{time.gmtime()} and \function{timegm()} are each others' inverse.
|
|
\end{funcdesc}
