5.2 calendar--General Date correlation function (1)

This module provides a general date-related operation function for the calendar. By default, Monday is the first day of the week, and Sunday is the last day of the week. the first day of the week can be set by the function setfirstweekday () function, for example, parameter input 6 is Sunday as the first day.

Class Calendar. Calendar (firstweekday=0)

Creates a Calendar object. The parameter firstweekday is an integer that indicates the day of the week on which the first week begins. 0 means Monday,6 means Sunday.

Example:

Import Calendar

Cal = Calendar. Calendar (0)

Print (CAL)

<calendar. Calendar Object at 0x02a30e30>

the Calendar class has the following instance methods:

Iterweekdays ()

Returns the iteration object of the week, typically used to output the daily ordinal of a week. The default is starting from 0 .

Example:

#python 3.4

Import Calendar

Cal = Calendar. Calendar (0)

Print (CAL)

Print (Cal.iterweekdays ())

For I in Cal.iterweekdays ():

Print (i)

The resulting output is as follows:

<calendar. Calendar Object at 0x02a50e30>

<generator Object Iterweekdays at 0x02ceb8c8>

Itermonthdates (year, month)

Returns the relevant date for the specified year and month, starting on the first day of the specified week of the month, and the day ending in the last week of the month.

Example:

#python 3.4

Import Calendar

Cal = Calendar. Calendar (0)

Print (CAL)

Print (Cal.itermonthdates (2015, 11))

For I in Cal.itermonthdates (2015, 11):

Print (i, end = ', ')

The resulting output is as follows:

<calendar. Calendar Object at 0x02d00e30>

<generator Object Itermonthdates at 0x02d6b8c8>

Example:

#python 3.4

Import Calendar

Cal = Calendar. Calendar (0)

Print (CAL)

For I in Cal.itermonthdays2 (2015, 11):

Print (i, end = ', ')

The resulting output is as follows:

<calendar. Calendar Object at 0x02ce0e30>
