In this paper, we share the specific code of Python to realize the student management system for your reference. The specific contents are as follows
To realize the transition from process-oriented to object-oriented, by changing the previous student management system to realize object-oriented, it also proves that process-oriented can be perfectly transitioned to object-oriented, thus making a step forward optimization for future program progress, which is convenient for future program changes.
The complete code is as follows:
Code in the student_main module
import student_tools
class Student(student_tools.StudentT):
def __init__(self):
self.user=['wangtaotao']
self.pwd=['123456']

print(" The account number or password is incorrect, please re-enter it ")
# Registration
def zhuce(self):
users=input(" Please enter the user name you want to register :")
pwds=input(" Please enter the password you want to register :")
self.user.append(users)
