一、输入/加密
#!/usr/bin/python
#coding:utf-8
import getpass
name = raw_input(‘请输入用户名：‘)
pwd = getpass.getpass(‘请输入密码：‘)
if name == "alex" and pwd == "cmd":
print "欢迎，alex！"
else:
print "用户名和密码错误"
二、enumrate
li = [11,22,33]
for k,v in enumerate(li, 1): print(k,v)print range(1, 10, 2)# 结果：[1, 3, 5, 7, 9]print range(30, 0, -2)# 结果：[30, 28, 26, 24, 22, 20, 18, 16, 14, 12, 10, 8, 6, 4, 2]原文：http://www.cnblogs.com/liwenzhen238/p/6185603.html
