Implementation of Student Address Book Management System with python

In this paper, we share the specific code of python to realize the student address book management system for your reference. The specific contents are as follows

Functional module analysis:

1. Home page (menu function)
Step 2 Add students
Step 3 Delete students
STEP 4 Modify students
5. Count the number of contacts in the address book
6. Get all student communication information

The code is as follows:

def main():
 while True:
 menu()
 number = int(input(" Please enter the sequence number of the operation to be implemented: "))
 if number==1:
  insert() # Add Students 
 if number==2:
  delete() # Delete students 
 if number==3:
  modify() # Modify students 
 if number==4:
  count() # Count the number of contacts in the address book 
 if number==5:
  disply() # Get all student communication information 
 if number==0:
  x=input(" Input yes Exit the system, enter any other characters without exiting :")
  if x == "yes":
  break


studentlist=[]

 Menu = """
