1.
定义一个get_constellation(month,date)函数,来获取出生日期。
2.
创建一个dates和constellations分别来储存对应的日和星座。
3.
用if语句判断输入的日数是否小于出生月份减一所对应的日数。
4.
如果是就返回月份减一所对应的星座,不是就返回出生月份所对应的星座。
python格式化日期的方法：可以利用time.asctime(time.local(time.time()))函数来格式化日期。如果我们要获取当前日期，可以利用时间函数time()来获取。
python中要把字符串转换成日期格式需要使用time模块中的strptime函数，例子如下：
import time
t = time.strptime('2016-05-09 21:09:30', '%y-%m-%d %h:%m:%s')
print(t)执行结果如下：
time.struct_time(tm_year=2016,
tm_mon=5,
tm_mday=9,
tm_hour=21,
tm_min=9,
tm_sec=30,
tm_wday=0,
tm_yday=130,
tm_isdst=-1)
函数说明：
第一个参数是要转换成日期格式的字符串，第二个参数是字符串的格式
函数官方文档如下：
help on built-in function strptime in module time:
strptime(...)
strptime(string, format) - struct_time
parse a string to a time tuple according to a format specification.
see the library reference manual for formatting codes (same as
strftime()).
commonly used format codes:
%y year with century as a decimal number.
%m month as a decimal number [01,12].
%d day of the month as a decimal number [01,31].
%h hour (24-hour clock) as a decimal number [00,23].
%m minute as a decimal number [00,59].
%s second as a decimal number [00,61].
%z time zone offset from utc.
%a locale's abbreviated weekday name.
%a locale's full weekday name.
%b locale's abbreviated month name.
%b locale's full month name.
%c locale's appropriate date and time representation.
%i hour (12-hour clock) as a decimal number [01,12].
%p locale's equivalent of either am or pm.
other codes may be available on your platform. see documentation for the c library strftime function.
