每个日期可以转成8位数字，比如 2017年12月4日 对应的就是 20171204。小明发现，自己的生日转成8位数字后，8个数字都没有重复，而且自他出生之后到今天，再也没有这样的日子了。请问小明的生日是哪天？

from datetime import date, timedeltasdate = date(1900, 1, 1)
edate = date.today()
delta = edate - sdate
new_str_day = []
count = 0
for i in range(delta.days + 1):day = sdate + timedelta(days=i)str_day = str(day).replace('-', '')flag = 0for x in str_day:'''which is right？？？'''# new_str = str_day.replace(x, '')# if len(new_str) == (len(str_day) - 1):#     flag += 1# if flag == 8:#     flag = 0#     count += 1#     print(str_day)if str_day.count(x) >= 2:breakelse:flag += 1count += 1if flag == 8:print(str_day)
print(count)
