激活虚拟环境后，`PATH` 变量会变成这样：

//// tab | Linux, macOS

```plaintext
/home/user/code/awesome-project/.venv/bin:/usr/bin:/bin:/usr/sbin:/sbin
```

这意味着系统现在会首先在以下目录中查找程序：

```plaintext
/home/user/code/awesome-project/.venv/bin
```

然后再在其他目录中查找。

因此，当你在终端中输入 `python` 时，系统会在以下目录中找到 Python 程序：

```plaintext
/home/user/code/awesome-project/.venv/bin/python
```

并使用这个。
