计算天数

程序示例：

# date = input('Enter a date: ')
# 2024-12-21
# year = int(date[0:4])
# month = int(date[5:7])
# day = int(date[8:])
date = input('Enter a date: ').split("-")
year = int(date[0])
month = int(date[1])
day = int(date[2])
count = 0
days = {1: 31, 2: 28, 3: 31, 4: 30, 5: 31, 6: 30, 7: 31, 8: 31, 9: 30, 10: 31, 11: 30,12: 31, }
if month == 1:count = day
else:for k, v in days.items():if k < month:count = count + vcount = count + day
print(count)
