今天带来了一个小程序——闰年识别
原理
我们都知道闰年的机制是“四年一闰，百年不闰，四百年一闰”，所以小程序如下所示：
year = input (“pleaz input year:” )
if (year % 100 == 0) and (year % 400 == 0) or (year % 100 == 1) and (year % 4 == 0):
print (“this is a leap year”)
else:
print (“this isn’t a leap year”)
包装
加上包装
var = 1
while var == 1 :
year = input (“pleaz input year:” )
if (year%100 == 0) and (year%400 == 0) or (year%100 == 1) and (year%4 == 0):
print (“this is a leap year”)
else:
print (“this isn’t a leap year”)
import time
for a in range (1,4):
time.sleep (0.2)
print “…”
time.sleep (0.2)
