實現(xiàn)一個python選課系統(tǒng)實例

import?sys,os    #程序主目錄  BASE_DIR?=?os.path.dirname(os.path.dirname(os.path.abspath(__file__)))  print(BASE_DIR)    #添加環(huán)境變量  sys.path.append(BASE_DIR)    from?core?import?main    if?__name__?==?'__main__':  ????a?=main.Run()  ????a.interactive()

import?hashlib  import?time    def?create_md():  ????m?=?hashlib.md5()  ????m.update(bytes(str(time.time()),encoding="utf-8"))  ????return?m.hexdigest()

import?sys,os???????　　  import?json　　　　　　#這里說一下json這個模塊，java之中也有應用，所以一些數(shù)據(jù)也可以給java去用。  import?pickle　　　　　    from?bin?import?course  from?core?import?uid    #數(shù)據(jù)庫文件路徑  db_DIR?=?course.BASE_DIR?+?r"db"  db_school?=?db_DIR?+?r"school"  db_teacher?=?db_DIR?+?r"teacher"  db_student?=?db_DIR?+?r"student"  db_classes?=?db_DIR?+?r"classes"  db_course?=?db_DIR?+?r"course"  db_admin?=?db_DIR?+?r"admin"  db_class_record?=?db_DIR?+?r"class_record"  db_class_grade?=?db_DIR?+?r"class_grade"    #基礎類，主要包括文件的讀寫操作  class?Baseclass(object):??#在python3中全部是新式類，但是建議還是這樣寫。在python2中存在經(jīng)典類和新式類；例如：class?Baseclass:?這種在python中是經(jīng)典類，而class?Baseclass(object):這樣是新式類。有關它們的區(qū)別，我會在下一篇博客中具體說明。
