生成200个10位的随机数（生成优惠券）：

__author__ = 'friday'

import random

def creat_num(num,long):

    str = 'qwertyuiopasdfghjklzxcvbnm1234567890!@#$%^&*_+'

    b = []

    for i in range(num):

        a = ''

        for j in range(long):

            a += random.choice(str)

        b.append(a)

    for i in range(len(b)):

        print(b[i])

if __name__ == '__main__':

    creat_num(200,10) 

判断有多少个英文单词：

import re

from collections import Counter

def word_count(txt):

    word_pattern = r'[a-zA-Z-]+'

    words = re.findall(word_pattern, txt)

    return Counter(words).items()

if __name__ == '__main__':

    txt = open('D:\\f.txt', 'r').read().lower()

    print word_count(txt)

为头像加数字:

__author__ = 'Kxrr'

from PIL import Image,ImageDraw,ImageFont

import random

msgNum = str(random.randint(1,99))

# Read image

im = Image.open('D:\\1.jpg')

w,h = im.size

wDraw = 0.8 * w

hDraw = 0.08 * w

# Draw image

font = ImageFont.truetype('D:\\1.ttc', 30) # use absolute font path to fix 'IOError: cannot open resource'

draw = ImageDraw.Draw(im)

draw.text((wDraw,hDraw), msgNum, font=font, fill=(255,33,33))

# Save image

im.save('D:\\kxrr_msg.png', 'png') 

有个目录，里面是你自己写过的程序，统计一下你写过多少行代码。包括空行和注释，但是要分别列出来。

import os

import re

def find_path(path):

    c = 0

    for i in os.listdir(path):

        py=os.path.join(path,i)

        a=open(py)

        commentline = 0

        blankline = 0

        lines = len(a.readlines())

        print "There are %d lines in %s" % (lines, py)

        for ii in a.readlines():   

            pattern = re.compile(r'(\s*)#')

            pattern1 = re.compile(r'(\s*)$')

            if pattern.match(ii):

                    commentline += 1

            if pattern1.match(ii):

                    blankline += 1

        print "blankline is:",blankline,"commentline is:",commentline

find_path('d://1')
