1.图片上添加文本

#!/user/bin/env python#coding:utf-8myPath='./media/'fontPath='./media/'inputFile='xwp.jpg'outputFile='output.jpg'import Image , ImageFont , ImageDraw    #先安装#打开图片Im=Image.open(myPath+inputFile)draw=ImageDraw.Draw(Im)#根据图片大小确定字体大小fontsize=min(Im.size)/4#加文字font=ImageFont.truetype(fontPath+ 'khmerOS.ttf',fontsize)draw.text((Im.size[0]-fontsize,0),'5',font=font,fill=(256,0,0))Im.save(myPath+outputFile,'jpeg')

2.生成随机数

#!/user/bin/env python#coding:utf-8import string,random#激活码中的字符和数字field=string.letters + string.digits#获得四个字母和数字的随机组合def getRandom():    return "".join(random.sample(field,6))#生成的每个激活码中有几组def concatenate(group):    return '-'.join(getRandom() for i in range(group))#生成n组激活码def generate(n):    return [concatenate(4) for i in range(n)]if __name__=='__main__':    print generate(5)

3.单词个数

#!/user/bin/env python#coding:utf-8import refrom collections import CounterFILESOURCE='./test.txt'def getMostCommonWord(articlefilesource):    '''    输入一个英文的纯文本文件，统计其中的单词出现的个数    :param articlefilesource:    :return:    '''    pattern=r'''[A-Za-z]+|\$?\d+%?$'''    with open(articlefilesource) as f:        r=re.findall(pattern,f.read())        return Counter(r).most_common()if __name__=='__main__':    print getMostCommonWord(FILESOURCE)
