日期大小比較令解決{strftime('%Y年%m月%d日')}出錯問題

大小比較代碼：

import datetime
import time
#將日期字符串轉為時間再比較，time，datetime,str
def valid_date(timestr):
    #獲取當前時間日期
    nowTime_str = datetime.datetime.now().strftime('%Y-%m-%d') 
    print(nowTime_str)
    #mktime參數為struc_time,將日期轉化為秒，
    e_time = time.mktime(time.strptime(nowTime_str,"%Y-%m-%d"))
    print(e_time)
    try:
        s_time = time.mktime(time.strptime(timestr, '%Y-%m-%d'))
        print(s_time)
        #日期轉化為int比較
        diff = int(s_time)-int(e_time)
        print(diff)
        if diff >= 0:
            return 1
        else:
            print('所查日期不能小於當前時間！！！')
            return 0
    except Exception as e:
        print(e)
        return 0
if __name__=='__main__':
    valid_date("2018-10-07")

解決報錯方案：

Traceback (most recent call last):
  File "E:/pycharm/WorkPlace/Graduation_project/Util/有用插件/日期比較.py", line 32, in <module>
    nowTime_str = datetime.datetime.now().strftime('%Y年%m月%d日')
UnicodeEncodeError: 'locale' codec can't encode character '\u5e74' in position 2: encoding error

更改為：

time.strftime('%Y{y}%m{m}%d{d} %H{h}%M{f}%S{s}').format(y='年',m='月',d='日',h='時',f='分',s='秒')
