python输入某年某月某日，判断这一天是这一年的第几天？

year=int(input("请输入年份："))
month=int(input("请输入月份："))
day=int(input("请输入日期："))
bmonth=(1,3,5,7,8,10,12)
smonth=(4,6,9,11)
pday=(0,31,59,90,120,151,181,212,243,273,304,334)
rday=(0,31,60,91,121,152,182,213,244,274,305,335)
if year<0:
    print("您输入的年份有误")
elif year>=0 and year%400==0 or year % 100 != 0 and year % 4 == 0:
    if month>12 or month<1:
        print("您输入的月份有误")
    else:
        if month in bmonth and day <=31 and day >0 or month in smonth and day <=30 and day >0 or month==2 and day<=29 and day>0:
            print("输入的日期为%d年的第%d天" % (year, int(rday[month - 1] + day)))
        else:
            print("您输入的日期有误")
else:
    if month>12 or month<1:
        print("您输入的月份有误")
    else:
        if month in bmonth and day <=31 and day >0 or month in smonth and day <=30 and day >0 or month==2 and day<=28 and day>0:
            print("输入的日期为%d年的第%d天" % (year, int(pday[month - 1] + day)))
        else:
            print("您输入的日期有误")

其实我有点疑问就是python的if语句可不可以连接多个or和and一起使用？这代码在PyCharm跑出来是没问题的
