python开发_calendar

biao199423

　　如果你用过linux，你可能知道在linux下面的有一个强大的calendar功能，即日历
　　在python中，同样也有这样的一个强大的calendar
　　下面是我做的demo：



1 #python中的calendar
2
3 import calendar
4
5 #返回指定年的某月
6 def get_month(year, month):
7     return calendar.month(year, month)
8
9 #返回指定年的日历
10 def get_calendar(year):
11     return calendar.calendar(year)
12
13 #判断某一年是否为闰年，如果是，返回True，如果不是，则返回False
14 def is_leap(year):
15     return calendar.isleap(year)
16
17 #返回某个月的weekday的第一天和这个月的所有天数
18 def get_month_range(year, month):
19     return calendar.monthrange(year, month)
20
21 #返回某个月以每一周为元素的序列
22 def get_month_calendar(year, month):
23     return calendar.monthcalendar(year, month)
24
25 def main():
26     year = 2013
27     month = 8
28     test_month = get_month(year, month)
29     print(test_month)
30     print('#' * 50)
31     #print(get_calendar(year))
32     print('{0}这一年是否为闰年？：{1}'.format(year, is_leap(year)))
33     print(get_month_range(year, month))
34     print(get_month_calendar(year, month))
35     
36 if __name__ == '__main__':
37     main()
　　运行效果：

　　再附上calendar.py的源码：
