python--每日一练-02

1、输入某年某月某日，判断这一天是这一年的第几天？

import re

date = input("请输入日期（**年**月**日）:")
dates = re.findall(r"\d+",date)  #使用正则提取数字
year = int(dates[0])
month = int(dates[1])
day = int(dates[2])
sum=0
leap = 0

if (year%400==0) or ((year % 4 == 0) and (year % 100 != 0)):  #判断是否是瑞年
        leap = 1
leaps = 28 + leap

months = (31,leaps,31,30,31,30,31,31,30,31,30,31)
if 0 < month <= 12:
        for i in range(month-1):
                sum += months[i]
        if 0 < day <= months[month-1]:
                sum += day
                print("it is the %dth day." % sum)
        else:
                print("day's data error")
                
else:
        print("month's data error")

2、输入三个整数x,y,z，请把这三个数由小到大输出。

import re

num = input("请连续输入三个数字（用“，”隔开）:")
nums = re.findall(r"\d+",num)  #使用正则提取数字
nums = [int(i) for i in nums]  #将提取到的数字转化为int类型

#使用冒泡排序算法
for i in range(len(nums)-1):
        for j in range(len(nums)-1-i):
                if nums[j]>nums[j+1]:
                        nums[j],nums[j+1] = nums[j+1],nums[j]   #python特有的交换方式
print("排序后：",nums)
