python数据库编程 Mysql实现通讯录

本文实例为大家分享了Mysql实现通讯录的具体代码，供大家参考，具体内容如下

#-*-code:utf-8-*-import pymysqldef CreateTable(): hcon=pymysql.connect(host=’localhost’,user=’root’,password=’lptpwd’,database=’contract’,charset=’utf8’) hcur=hcon.cursor() hcur.execute(’drop table if exists contractlist’) ctable=’’’ create table contractlist ( ID int(10) primary key, NAME varchar(20) not null, TELF char(11) not null, TELS char(11), OTHER varchar(50) )engine=myisam charset=utf8; ’’’ hcur.execute(ctable) hcur.close() hcon.close() def AddInfo(hcon,hcur): id=int(input(’please input ID: ’)) name=str(input(’please input Name: ’)) telf=str(input(’please input Tel 1: ’)) tels=str(input(’please input Tel 2: ’)) other=str(input(’please input other: ’)) sql='insert into contractlist(id,name,telf,tels,other) values(%s,%s,%s,%s,%s)' try: hcur.execute(sql,(id,name,telf,tels,other)) hcon.commit() except: hcon.rollback() def DeleteInfo(hcon,hcur): SelectInfo(hcon,hcur) did=int(input(’please input id of delete: ’)) sql='delete from contractlist where id=%s' 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: ’)) sqlname='update contractlist set name=%s where id=%s' name=str(input(’please input Name: ’)) try: hcur.execute(sqlname,(name,did)) hcon.commit() except: hcon.rollback() sqltelf='update contractlist set telf=%s where id=%s' telf=str(input(’please input Tel 1: ’)) try: hcur.execute(sqltelf,(telf,did)) hcon.commit() except: hcon.rollback() sqltels='update contractlist set tels=%s where id=%s' tels=str(input(’please input Tel 2: ’)) try: hcur.execute(sqltels,(tels,did)) hcon.commit() except: hcon.rollback() sqlothers='update contractlist set other=%s where id=%s' other=str(input(’please input other: ’)) try: hcur.execute(sqlothers,(other,did)) hcon.commit() except: hcon.rollback() def SelectInfo(hcon,hcur): hcur.execute('select * from contractlist') result=hcur.fetchall() ptitle=(’ID’,’Name’,’Tel 1’,’Tel 2’,’Other’) print(ptitle) for findex in result: print(findex) print(’’) 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(): #CreateTable() hcon=pymysql.connect(host=’localhost’,user=’root’,password=’ltb12315’,database=’contract’,charset=’utf8’) hcur=hcon.cursor() while(True): sel=Meau() if(sel==1): SelectInfo(hcon,hcur) elif(sel==2): AddInfo(hcon,hcur) elif(sel==3): UpdateInfo(hcon,hcur) elif(sel==4): DeleteInfo(hcon,hcur) elif(sel==5): os.system(’cls’) else: break print(’-------------------------’) hcur.close() hcon.close() if __name__=='__main__': main()
