如果你不去停用 `philosophers-stone` 的虚拟环境，当你在终端中运行 `python` 时，它会尝试使用 `philosophers-stone` 中的 Python。

<div class="termy">

```console
$ cd ~/code/prisoner-of-azkaban

$ python main.py

// 导入 sirius 报错，它没有安装 😱
Traceback (most recent call last):
    File "main.py", line 1, in <module>
        import sirius
```

</div>

但是如果你停用虚拟环境并激活 `prisoner-of-askaban` 的新虚拟环境，那么当你运行 `python` 时，它会使用 `prisoner-of-askaban` 中的虚拟环境中的 Python。

2. **Commits**:
   - Write clear messages: what changed and why (e.g., “Refactor S3 API handler to reduce latency so that requests process 20% faster”).
   - Rebase to tidy commits before submitting (e.g., `git rebase -i main` to squash typos or reword messages), unless multiple contributors worked on the branch.
   - Keep PRs focused—one feature or fix. Split large changes into multiple PRs.

3. **Testing**:
