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

これは、OSが他のディレクトリを探すより前に、最初に以下のディレクトリ中でプログラムを探し始めることを意味します：

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

そのため、ターミナルで `python` と入力した際に、OSはPythonプログラムを以下のパスで発見し、使用します。

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

啟用虛擬環境後，`PATH` 變數會變成這樣：

//// tab | Linux, macOS

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

這意味著系統現在會首先在以下目錄中查找程式：

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

然後再在其他目錄中查找。

因此，當你在終端機中輸入 `python` 時，系統會在以下目錄中找到 Python 程式：

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

並使用這個。

////

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。
