Python中的日历函数 |设置 2(monthrange(), prcal(), weekday()…)
Set 1 中讨论了一些日历功能
1. monthrange(year, month) :- 该函数返回两个整数，第一个是星期的起始天数（0 为星期一），第二个是该月的天数。
2. prcal(year, w, l, c) :- 该函数也打印特定年份的日历，但不需要“打印”操作来执行。
# Python code to demonstrate the working of
# monthrange() and prcal()
# importing calendar module for calendar operations
import calendar
# using monthrange() to print start week day and
# number of month
print ("The start week number and no. of days of month : ",end="")
print (calendar.monthrange(2008, 2))
# using prcal() to print calendar of 1997
print ("The calendar of 1997 is : ")
calendar.prcal(1997, 2,1,6)
输出：
The start week number and no. of days of month : (4, 29)
The calendar of 1997 is :
1997

3. prmonth(year, month, w, l) :- 该函数也打印特定年份的月份，但不需要“打印”操作来执行此操作。
4. setfirstweekday(num) :- 这个函数设置星期的开始数。
# Python code to demonstrate the working of
# prmonth() and setfirstweekday()
# importing calendar module for calendar operations
import calendar
# using prmonth() to print calendar of 1997
print ("The 4th month of 1997 is : ")
calendar.prmonth(1997, 4, 2, 1)
# using setfirstweekday() to set first week day number
calendar.setfirstweekday(4)
print ("\r")
# using firstweekday() to check the changed day
print ("The new week day number is : ",end="")
print (calendar.firstweekday())
输出：
The 4th month of 1997 is :
April 1997

The new week day number is : 4
5. weekday(year, month, date) :- 此函数返回其参数中指定的日期的星期数（0 是星期一）。
# Python code to demonstrate the working of
# weekday()
# importing calendar module for calendar operations
import calendar
# using weekday() to print day number of date
print ("The day number of 25 April 1997 is : ",end="")
print (calendar.weekday(1997,4,25))
输出：
The day number of 25 April 1997 is : 4
