Hi,

I was reading this page on the website https://plotly.com/python/getting-started/ which I think is this file doc/python/getting-started.md (hope i'm right about the file) to install extra dependencies (namely kaleido) without waiting for the code to bring the error.
But when I used the little copy icon, the line came with the little $ and as it is not in every line of code to copy I was wondering whether it was meant to be here and if the $ could be removed for a smoother experience (it's like one second to remove them so I can understand if you don't see this as an inconvenience).

TLDR
There's some lines of code prefixed with a little $ that gets copied when you use the copy icon and I was wondering if removing them would be nicer for the docs users.

Thanks for your time and the awesome lib !
