Abstract
Now, with the development of network, the education industry is also developing in the direction of network. The original education industry mainly implemented the offline teaching mode. Teachers completed the training of students from teaching to testing through offline course teaching, assignment arrangement and examination organization. This way still continues to this day, which proves that its role is effective. However, for the management of teachers, with the gradual growth of China’s population and the increase of the number of school-age students, the traditional offline method is used to detect the learning situation of students. It is necessary to divide the examination classes, arrange the invigilator, etc., and mark the examination results of students one by one after the examination, For teachers, the pressure of management is gradually increasing. In such a state of development, the development of computer informatization based on network to realize the assembly of examination papers, online examination and automatic marking and evaluation will gradually grow up. By inputting single-choice questions, multiple-choice questions, judgment questions and question and answer questions in the computer, and then automatically selecting topics with different degrees of difficulty through the system for test paper assembly, the whole test paper generation process can be smooth and can better provide powerful help services for teachers.
Based on the current development status of online self-evaluation system such as online test paper assembly, an online self-evaluation system is developed by using Python technology. Through this system, teachers can realize online question bank management, test paper generation and examination management, and student users can also realize online examination and examination score viewing.
Key words: Online independent evaluation; Online examination; Python
