Python日历模块 |第一个工作日（）方法

日历模块允许像程序一样输出日历，并提供与日历相关的附加有用功能。 Calendar 模块中定义的函数和类使用理想化的日历，当前的公历在两个方向上无限扩展。

在Python中， calendar.firstweekday()是calendar 模块中提供的用于简单文本日历的函数。

firstweekday()方法用于获取每周开始的工作日的当前设置。

Syntax: firstweekday()
Parameter: no parameter

代码#1：

# Python program to explain working of firstweekday() method
  
# importing calendar module
import calendar
  
# default firstweekday
print("Default First weekday is - ", calendar.firstweekday())
  
# setting 2nd day as firstweekday
calendar.setfirstweekday(2)
  
# print firstweekday
print("First weekday after modification is - ", calendar.firstweekday())

输出：

Default First weekday is -  6
First weekday after modification is -  2

代码 #2：使用 prmonth() 方法解释 firstweekday() 方法的工作

# Python code to demonstrate the working of 
# firstweekday() with help of prmonth() method
  
# 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("First weekday after modification is - ",
                        calendar.firstweekday())

输出：

The 4th month of 1997 is :
