Broadly speaking, BBEdit doesn't color quite as extravagantly as Atom. This is out-of-the-box BBEdit Dark, showing a piece of Python:

def is a language keyword, as is the decorator; and the single string is colored. However BBEdit doesn't know anything about Python _per se_ so it doesn't know that show() is a function name, or list_of_items is a variable. So they're just regular text.
That said: if you do 'bbedit --maketags' on the command line, you get a ctags file created, and now it looks like this:

Which is closer to what you probably want. I don't like ctags coloring most of the time, I think it over-does it on detecting symbols:

But to each their own.
Hope that helps,
