Python初识

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)

 

三、range和xrange

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]
