使用python生成一个图片验证码，随机的，可以由于验证人机和别的啊，很方便很简单

导入模块

import random
from PIL import Image,ImageFont,ImageDraw

生成随机验证码

def rndtxt():
    txt_list = []
    # 大写字母
    txt_list.extend([i for i in range(65,90)])
    # 小写字母
    txt_list.extend([i for i in range(97,123)])
    # 数字
    txt_list.extend([i for i in range(48,57)])
    return chr(txt_list[random.randint(0,len(txt_list)-1)])

作为待会生成的图片背景色和字体色

def rndbgcolor():
    # 背景颜色
    return (random.randint(64,255),random.randint(64,255),random.randint(64,255))

def rndtxtcolor2():
    # 字体颜色
    return (random.randint(32,127),random.randint(32,127),random.randint(32,127))

进行生成打印验证码并以图片的形式打开，不保存图片文件，仅用于一时的验证码验证

def code():
    weight = 240
    hight = 60
    image = Image.new('RGB',(weight,hight),(255,255,255))
    font = ImageFont.truetype('msyh.ttc',36)
    draw = ImageDraw.Draw(image)

    # 填充背景颜色
    for x in range(weight):
        for y in range(hight):
            draw.point((x,y),fill=rndbgcolor())

    # 生成随机验证码
    for T in range(4):
        rndtxt_2 = rndtxt()
        print(rndtxt_2)       # 打印验证码的值
        draw.text((60 * T + 10,10),rndtxt_2,font=font,fill=rndtxtcolor2())
    image.show()

        draw.text((60 * T + 10,10),rndtxt_2,font=font,fill=rndtxtcolor2())
    image.show()
