python提取微信好友用户的信息非常方便，根据itchat这个包！

1）首先获取微信中所有的好友信息

img_relative_dir = './wechat_friends/'
    
    def get_all_friends_from_wechat():
        # auto login wechat web
        itchat.auto_login(hotReload=True)
        friends = itchat.get_friends(update=True)
        # download all friends
        order = 0
        # img_relative_dir = './wechat_friends/'
        if not os.path.exists(img_relative_dir):
            os.mkdir(img_relative_dir)
    
        for i in friends:
            img = itchat.get_head_img(i["UserName"])
            with open(img_relative_dir + str(order) + ".jpg", 'wb') as file:
                file.write(img)
                file.close()
                order += 1

2）将下载的头像，拼成一张大图：

def make_pic():
        line = 0
        row = 0
        length = len(os.listdir(img_relative_dir))
        each_size = int(math.sqrt(float(900 * 900) / length))
        lines = int(900 / each_size)
        image = Image.new('RGB', (900, 900), 'white')
    
        # make all pic to big pic
        for index in range(0, length):
            try:
                img = Image.open(img_relative_dir + str(index) + ".jpg")
            except IOError:
                print("image no found error")
            else:
                img = img.resize((each_size, each_size), Image.ANTIALIAS)
                image.paste(img, (line * each_size, row * each_size))
                line += 1
                if line == lines:
                    line = 0
                    row += 1
            image.save(img_relative_dir + "my_all_friends.jpg")
        image.show()
