# 入口函数
if __name__ == ‘__main__‘:
    s_date = input("Please input teh date(YYYYMMDD):")
    year = int(s_date[0: 4])   # 年
    month = int(s_date[4: 6])  # 月 
    day = int(s_date[6:8])     # 日
    # 每月的天数
    month_day = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]
    count = 0
    if year % 100 == 0 and year % 400 == 0:
        # 润年（2月有29天）
        month_day[1] = 29
    elif year % 4 == 0 and year % 100 != 0:
        # 润年（2月有29天）
        month_day[1] = 29
    if (day > month_day[month - 1]) or (month > 12):
        # 输入的日期有误
        print("Input Date Error.")
        exit()
    for m in range(month - 1):
        count += month_day[m]
    count += day

    print("%s is %dth day." % (s_date, count))

Please input teh date(YYYYMMDD):20200618
