python-打印简单公司员工信息表
要求，输入name不为空，输入次数最多3次，3次后跳出程序；
知识点：
raw_input
str转int
whil
if elif else continue break
for
导入模块
引用变量值
格式化输出
vim
#!/usr/bin/env python
import sys
user_name = "carson"
this_year = 2014
counter = 0
while True:
if counter < 3:
name = raw_input("please input your name:").strip()
if len(name) == 0:
print "empty name , please input your name again!"
continue
elif name == user_name:
pass
print "welcome to login system!"
else:
print "%s is a not valid user, please try again!" % name
counter = counter + 1
continue
break
else:
print "Your input 3 times!"
sys.exit()
break
age = int(raw_input("How old are you?"))
sex = raw_input("please input your sex:")
hobby = raw_input("Do you hava any hobbies?")
information = '''Information of company staff
Name :%s
Age :%d
Sex :%s
Hobby:%s
''' % (name,age,sex,hobby)
print information
输入3次，退出程序！ # python carson.by please input your name:a a is a not valid user, please try again! please input your name:b b is a not valid user, please try again! please input your name:c c is a not valid user, please try again! Your input 3 times!
输入空白字符，提示一直输入 # python carson.by please input your name: empty name , please input your name again! please input your name: empty name , please input your name again! please input your name: empty name , please input your name again! please input your name: empty name , please input your name again! please input your name: empty name , please input your name again! please input your name: empty name , please input your name again! please input your name: empty name , please input your name again! please input your name: empty name , please input your name again! please input your name: empty name , please input your name again!
输入正确：
please input your name:carson welcome to login system! How old are you?23 please input your sex:M Do you hava any hobbies?football Information of company staff Name :carson Age :23 Sex :M Hobby:football
在判断输入次数的还有一种方法是利用for循环：
#!/usr/bin/env python
import sys
user_name = "carson"
while True:
name = raw_input("please input your name:").strip()
if len(name) == 0:
print "empty name , please input your name again!"
continue
for i range(1,3):
name = raw_input("please input your name:").strip()
if name == user_name:
pass
print "welcome to login system!"
else:
print "%s is a not valid user, please try again!" % name
continue
break
else:
print "Your input 3 times!"
sys.exit()
break
age = int(raw_input("How old are you?"))
sex = raw_input("please input your sex:")
hobby = raw_input("Do you hava any hobbies?")
information = '''Information of company staff
Name :%s
Age :%d
Sex :%s
Hobby:%s
''' % (name,age,sex,hobby)
print information
