I recently downloaded and installed Python 3.9 because I wanted to run a website scraper to more easily organize recipes found online.我最近下载并安装了 Python 3.9，因为我想运行一个网站抓取工具来更轻松地组织在线找到的食谱。 However, when I try to run pip it says it doesn't recognize it (and I have tried editing the path but every video or site I find has different information).但是，当我尝试运行pip它说它无法识别它（我尝试编辑路径，但我发现的每个视频或网站都有不同的信息）。

Even a basic check of my Python version comes back with no results:即使对我的 Python 版本进行基本检查也没有结果：

I have uninstalled and reinstalled Python 3.9 but to no avail.我已经卸载并重新安装了 Python 3.9，但无济于事。 There is also no scripts file within my python file and my computer doesn't even seem to recognise that Python is installed.我的 python 文件中也没有脚本文件，我的计算机似乎甚至无法识别安装了 Python。
