这个程序相当于一次性用品,怎么让他能重复使用.
temp = input('请输入一个年份：')while not temp.isdigit():
temp = input("抱歉，您的输入有误，请输入一个整数：")
year = int(temp)
if year/400 == int(year/400):
print(temp + ' 是闰年！')
else:
if (year/4 == int(year/4)) and (year/100 != int(year/100)):
print(temp + ' 是闰年！')
else:
print(temp + ' 不是闰年！') while True:
temp = input('请输入一个年份：')
while not temp.isdigit():
temp = input("抱歉，您的输入有误，请输入一个整数：")
year = int(temp)
if year/400 == int(year/400):
print(temp + ' 是闰年！')
else:
if (year/4 == int(year/4)) and (year/100 != int(year/100)):
print(temp + ' 是闰年！')
else:
print(temp + ' 不是闰年！')
