得到禮物一個月的日期在日期

Question

列表和差異如何去打印這些：

1. 在任何給定的時間，我應該能夠回到本月份的日期列表中。 例如。由於這是3月份，我想打印一份清單[20140301, ...,20140331]。

2. 查找當前日期和當月第一天的天數差異。

   例如今天是3月4日。我應該能夠打印提前

Answer 1

這裏是你可以在Python 2.7.3

from datetime import date 
import calendar 
today = date.today() 

first_of_month = today.replace(day=1) 
_, number_of_days_in_month = calendar.monthrange(first_of_month.year, first_of_month.month) 

for i in range(1, number_of_days_in_month+1): 
    newdate = today.replace(day = i) 
    print newdate #prints all dates in months 

#Lets calculate difference between 14th of this month and 1st 
randomdate = today.replace(day=14) 
delta = randomdate - first_of_month 
print delta.days
