#version: python3.2.5 #author: ‘FTL1012‘ #time: 2017/12/6 17:20 #name=hhh 这个是错误的,因为没有用单引号/双引号括起来,当做一个变量赋值给 name = input("please input the name:") age = input("please input the age:") tel = input("please input the tel:") if age.isdigit(): if tel.isdigit(): age = int(age) #age必须是数字 tel = int(tel) #tel必须是数字 else: exit ("something wrong...") msg = ''' ---------info of %s --------- name: %s age : %d tel : %d ---------end of %s --------- ''' %(name, name, age, tel, name) print(msg)
