#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)
