python常用模块（datetime）之利用sxtwl模块实现阴阳历生日换算

import sxtwl
from datetime import datetime

lunar = sxtwl.Lunar()  

def fun1(day1):
    a = datetime.now().year
    date1 = datetime.strptime(day1,'%Y-%m-%d')

    day_diernian = lunar.getDayByLunar(a+1, date1.month, date1.day)
    print("你的生日在本年的阳历生日为:", day.y, "年", day.m, "月", day.d, "日")
    print("你的生日在第二年的阳历生日为:", day_diernian.y, "年", day_diernian.m, "月", day_diernian.d, "日")
    
    global year
    global month
    global day11

    month = day.m
    day11 = day.d

    elif j<0:
        #现在到第二年1月1号的天数
        year += 1
        days4 = datetime(year,1,1)
