Python 参考

运行 ZJUI-Learn 问题或元素时，这些帮助程序在 Python 环境中可用。它们按类别组织。最常用的帮助程序是评分、转换 和问题 帮助程序。

以下是导入助手的推荐方法：

import prairielearn as pl
from prairielearn.colors import Y
from prairielearn.to_precision import Z
import prairielearn.sympy_utils as psu

???信息“更多信息”

You can use the following import to access most of the helpers:

```python
from prairielearn import ...
```

These modules must be imported directly:

```python
from prairielearn.colors import Y
from prairielearn.to_precision import Z
from prairielearn.sympy_utils import Z
```

You should **not** directly import the remaining dotted modules (e.g. `prairielearn.conversion_utils`), as they do not have a stable interface.
