When adding doctests to my markdown, I have to write something like

```python
>>>import numpy
>>>np.sum([1, 2])
3
```

This works fine with doctest. However, when I render the markdown page on Github, it’s difficult to copy/paste the example, as the interactive Python parts (such as >>>) are still there.

For instance, on the Python documentation for doctest itself: https://docs.python.org/3/library/doctest.html#how-are-docstring-examples-recognized one can click the button ‘Hide the prompts and output’, which makes copying easy. Can the same be achieved in Github markdown rendering?
