序列乘法示例与成员资格验证示例

13年前 
cur =raw_input("input you real name:")    screen_width=80  box_width = len(cur)+6  left_width = (screen_width-box_width)//2    序列乘法示例
print  print ' '*left_width+'+'+'-'*(box_width-6)+ '+'  print ' '*left_width+'|'+' '*len(cur)   +   '|'  print ' '*left_width+'|'        +cur+       '|'  print ' '*left_width+'|'+' '*len(cur)   +   '|'  print ' '*left_width+'+'+'-'*(box_width-6)+ '+'  print
通过利用乘法标签'*'  打印出来的效果是：
  input you real name:zhang san                                    +---------+                                  |         |                                  |zhang san|                                  |         |                                  +---------+  
成员资格验证示例
>>> users = [['admin','admin'],['zzp','zzp'],['plllp','plllp']]  >>> username = raw_input("input you username:")  input you username:zzp  >>> userpass = raw_input("input you password")  input you passwordzzp  >>> if [username,userpass] in users:print'user is checked'  user is checked  >>>
