1. 猜數字

#!/usr/bin/env python

#coding:utf-8

import random

num = random.randint(0,9)

while True:

    user_num = raw_input("please input a num: ")

    user_num = int(user_num)

    if user_num == num:

        print 'success'

        for i in range(1,8):

            print '*'*i

        break

    else:

        print 'error'

2.創建文件夾

#!/usr/bin/env python

#coding:utf-8

import os

depts = ['銷售部','人事部','技術部']

for dept in depts:

    try:

        os.mkdir(dept)

    except OSError as e:

        print '文件[%s]已經存在,因爲 [%s]' % (dept,e.strerror)
