import MySQLdb
import MySQLdb.cursors
db = MySQLdb.connect(host='localhost', user='root', passwd='root', db='user',cursorclass=MySQLdb.cursors.DictCursor)
cur = db.cursor()def staffInfo(Table):sql = 'select * from ' + Tablecur.execute(sql)EmployeeInfo = cur.fetchall()EmployeeInfo = list(EmployeeInfo)findName = input('Pelase enter name who you want to serch(if you need to find all, please input All):')if findName == 'All':print(EmployeeInfo)else:for staff in EmployeeInfo:if staff['user_name'] == findName:print("ID: %(user_id)s, Name: %(user_name)s,Employee Number: %(employee_number)s" %staff)breakelse:print('no this staff')}
3.4用戶刪除信息模塊 代碼如下：
import MySQLdb
import MySQLdb.cursors

cur = db.cursor()def Delete():name = input('Please enter the name of the employee you want to delete:')sql = 'delete from users where user_name = %s'try:cur.execute(sql, [name])db.commit()print('delete success')except Exception as e:db.rollback()print(e)# cur.close()# db.close()'''for staff in Table:if staff['name'] == name:# 查找索引Index = Table.index(staff)del Table[Index]print('Success')break
