这个错误提示是因为在 DataFrame 中找不到名为 `开奖号码（红色）` 的列。请确保该列名称正确无误，或者检查一下 Excel 文件中是否存在该列。可以使用 `df.columns` 查看 DataFrame 中所有列的名称，以确认列名是否正确。如果列名正确但仍出现此错误，可以尝试将列名用双引号或单引号括起来，例如：

plt.scatter(df['期号'], df['开奖日期'], df['开奖号码（红色）'], df['开奖号码（蓝色）'], df['总销售额（元）'])

修改为：

plt.scatter(df['期号'], df['开奖日期'], df["开奖号码（红色）"], df['开奖号码（蓝色）'], df['总销售额（元）'])

或者：

plt.scatter(df['期号'], df['开奖日期'], df['开奖号码（红色）'], df['开奖号码（蓝色）'], df['总销售额（元）'])

这个错误提示是因为连接MySQL数据库时，用户名或密码不正确，你需要检查一下你的用户名和密码是否正确。同时，也需要确保你的MySQL服务器已经启动，并且允许远程连接。

如果你忘记了MySQL的用户名和密码，可以尝试使用以下命令来重置密码：

1. 停止MySQL服务

sudo service mysql stop

2. 以跳过授权方式启动MySQL

sudo mysqld_safe --skip-grant-tables --skip-networking &

3. 使用root用户登录MySQL

mysql -u root

4. 切换到mysql数据库

use mysql;

5. 更新root用户的密码

update user set authentication_string=password('your_new_password') where user='root' and Host ='localhost';

6. 刷新权限

flush privileges;

7. 退出MySQL并重新启动服务

exit;
sudo service mysql start

然后，你可以使用新的密码来连接你的MySQL数据库了。

这个错误是由于selenium无法找到Firefox可执行文件引起的。在使用selenium的Firefox驱动程序时，需要指定正确的Firefox可执行文件路径。

要解决这个问题，你可以尝试以下几种方法之一：

1. 指定Firefox可执行文件路径：在创建WebDriver对象时，通过`executable_path`参数指定正确的Firefox可执行文件路径。例如：

   from selenium import webdriver

   driver = webdriver.Firefox(executable_path='path_to_firefox_executable')

请确保`path_to_firefox_executable`是你的系统上实际的Firefox可执行文件路径。

2. 更新或重新安装Firefox浏览器：确保你的Firefox浏览器是最新版本，并且与你使用的selenium版本兼容。如果已经安装了最新版本的Firefox，请尝试重新安装它。

3. 检查Firefox驱动程序版本：确保你使用的selenium库和Firefox驱动程序是兼容的。如果你使用了最新版本的selenium，请确保下载并使用对应版本的Firefox驱动程序。

请根据你的具体情况选择适合你的解决方法。希望能帮到你！如果还有其他问题，请随时提问。
