python程序员入职第一天_在python中查找每月的第一天

I'm trying to find the first day of the month in python with one condition: if my current date passed the 25th of the month, then the first date variable will hold the first date of the next month instead of the current month. I'm doing the following:

import datetime

todayDate = datetime.date.today()

if (todayDate - todayDate.replace(day=1)).days > 25:

x= todayDate + datetime.timedelta(30)

x.replace(day=1)

print x

else:

print todayDate.replace(day=1)

is there a cleaner way for doing this?

解决方案

This is a pithy solution.

import datetime

todayDate = datetime.date.today()

if todayDate.day > 25:

todayDate += datetime.timedelta(7)

print todayDate.replace(day=1)

One thing to note with the original code example is that using timedelta(30) will cause trouble if you are testing the last day of January. That is why I am using a 7-day delta.
