Vi. Introduction of main modules

1. Manager class

Include Create school (print school), create course (print course), create class (print Class), create learner (print learner), create instructor (print instructor)

Where the learner method is created, it is called again when the learner authenticates the sign-in feature;

2, Student class

# object Private parameter (name)
#方法: Print Current learner information, select course (buy course), learn manage (learn by module, submit job), submit job, view results

3, Teacher class

# object Private parameter (name)
#方法: Class management, creating Class records (print Course records), grading assignments

4, Datapickle class

# object Private parameter (path)
# method: Dump, load
