How would I transfer code from a notebook to this forum?
From within a Jupyter notebook, if I do Edit > Copy Cells, followed by Edit > Paste Cells Above (or Below), it works. But Edit > Copy Cells does not copy to the clipboard in 'code mode'... It works in 'markdown mode', but the demarcation between the cell input/output is not clear. There has got to be a simple way to transfer a notebook's content to this forum to illustrate a question. What is it?
