打印万年历
要求：日历程序可以打印出任何一年的日历，程序运行后输入一个年份，如输入2017年，打印2017年全年的日历。
提示：(1)注意闰年在判定
(2)求某月在最大天数
(3)求某月1号是星期几
(4)循环打印每一个月的日历
def print_calendar(year):
# 循环12个月
for month in range(1, 13):
# 输出月份和星期几的表头
print("{0}年{1}月".format(year, month))
print("日 一 二 三 四 五 六")
# 计算该月第一天是星期几
first_day = datetime.date(year, month, 1).weekday()
# 计算该月的天数
days_in_month = 31
if month == 2:
if year % 4 == 0 and year % 100 != 0 or year % 400 == 0:
days_in_month = 29
else:
days_in_month = 28
elif month in [4, 6, 9, 11]:
days_in_month = 30
# 输出日历
for i in range(first_day):
print(" ", end="")
for day in range(1, days_in_month + 1):
print("{0:2d} ".format(day), end="")
if (day + first_day) % 7 == 0:
print()
print()
