python数据库编程 ODBC方式实现通讯录

Python 数据库编程，ODBC方式实现通讯录，供大家参考，具体内容如下

#-*-coding:utf-8-*-
import pyodbc
import os
def SelectInfo(hcon,hcur):
 hcur.execute('select * from PassMapT')
 ptitle=('ID','Item','Pwd','other')
 print(ptitle)
 result=hcur.fetchall()
 for item in result:
 print(item)
 print('')

def AddInfo(hcon,hcur):
 id=int(input('please input ID: '))
 item=str(input('please input Item: '))
 pwd=str(input('please input Tel 1: '))
 other=str(input('please input Other: '))
 sql="insert into PassMapT(id,item,pwd,other) values(?,?,?,?)"
 try:
 hcur.execute(sql,(id,item,pwd,other))
 hcon.commit()
 except:
 hcon.rollback()

def DeleteInfo(hcon,hcur):
 SelectInfo(hcon,hcur)
 did=int(input('please input id of delete: '))
 sql="delete from PassMapT where id=?"
 try:
 hcur.execute(sql,(did,))
 hcon.commit()
 except:
 hcon.rollback()

def UpdateInfo(hcon,hcur):
 SelectInfo(hcon,hcur)
 did=int(input('please input id of update: '))
 
 sqlitem="update PassMapT set item=? where id=?"
 item=str(input('please input Item: '))
 try:
 hcur.execute(sqlitem,(item,did))
 hcon.commit()
 except:
 hcon.rollback()
 
 sqlpwd="update PassMapT set pwd=? where id=?"
 pwd=str(input('please input Pwd: '))
 try:
 hcur.execute(sqlpwd,(pwd,did))
 hcon.commit()
 except:
 hcon.rollback()
 
 sqlother="update PassMapT set other=? where id=?"
 other=str(input('please input other: '))
 try:
 hcur.execute(sqlother,(other,did))
 hcon.commit()
 except:
 hcon.rollback()
 
def Meau():
 print('1.diaplay')
 print('2.add')
 print('3.update')
 print('4.delete')
 print('5.cls')
 print('0.exit')
 sel=9
 while(sel>5 or sel<0):
 sel=int(input('please choice: '))
 return sel

def main():
 hcon = pyodbc.connect(r'DRIVER={SQL Server Native Client 11.0};SERVER=127.0.0.1;DATABASE=PasswordMap;UID=sa;PWD=lptpwd')
 hcur=hcon.cursor()

 elif(sel==3):

 elif(sel==4):
 DeleteInfo(hcon,hcur)
 elif(sel==5):
 os.system('cls')
 else:
 break
 hcur.close()
 hcon.close()

if __name__=='__main__':
 main()
