python PIL 模块

最近看了下PIL模块，看了下别人是如何生成验证码数据集

参考 https://www.cnblogs.com/tsboy/p/8862707.html

    random_upper = chr(random.randint(65,90))
    random_str = random.choice([random_number,random_low,random_upper])
    return random_str

    #font = ImageFont.truetype("simsun.ttc",size=random.randint(20,30))
    #写验证码

        random_char = RandomStr()

        draw.arc((x, y, x + 4, y + 4), 0, 90, fill=RandomColor())
    name = str(k) + '.png'
    image.save(name, 'png')

if __name__ == '__main__':
    for i in range(100):
        Drawsomethings(k = i)
