Abstract

With the rapid development of modern economy and the continuous improvement and upgrading of information technology, the management of traditional data information is upgraded to the management mode of software storage, induction and centralized processing of data information. This Python based computer network online examination system was born in this environment. It can help managers deal with huge data information in a short time. Using this software tool can help managers improve transaction processing efficiency and achieve twice the result with half the effort. This Python based computer network online examination system uses the current mature and perfect Vue technology, uses the cross platform Java language that can develop large commercial websites, and MySQL database, one of the most popular RDBMS application software, for program development. The computer network online examination system based on Python has three roles: administrator, teacher and student. Administrator functions include personal center, student management, teacher management, online examination management, test question management and examination management. Both teachers and students can register and log in. Teachers are mainly responsible for managing students, managing online exams, managing test questions, and viewing students' wrong question books and test records. Students mainly refer to the exam and view their own wrong question books and test records. The development of computer network online examination system based on Python is designed according to the needs of operators. The interface is simple and beautiful, and the layout of functional modules is consistent with that of similar websites. When the program realizes the basic required functions, it also provides some practical solutions for the security problems faced by data information. It can be said that the program not only helps managers deal with work affairs efficiently, but also realizes the integration, standardization and automation of data information.

Key Words：Computer network online examination system based on Python; Vue technology; MySQL； automation
