Feature or enhancement

Proposal:

I made a custom _colorize theme to try making my REPL syntax highlighting look similar to my text editor's.

This is the theme I used:

theme_with_dim_operators = default_theme.copy_with( syntax=Syntax( keyword=ANSIColors.GREEN, builtin=ANSIColors.BLUE, comment=ANSIColors.INTENSE_YELLOW, string=ANSIColors.CYAN, number=ANSIColors.CYAN, definition=ANSIColors.BLUE, soft_keyword=ANSIColors.BOLD_GREEN, ), )

I then used this example code to check the highlighting between the two:

from math import pi print(f"Welcome to Python {pi:.2f}") name = None if name is None: print("It's", True)

Pasting that code in my text editor (vim), looks like this:

Pasting the same code in the REPL, looks like this:

The granularity with syntax highlighting needs to stop somewhere, but I feel it would be nice to add a bit more granularity than is currently supported by _colorize.

In particular, it would be nice to distinguish between:

1. Syntax keywords in general (if, is, def, for, with, etc.)
2. Keywords that are variables (True, False, None)
3. Imports in particular (from, import)

I feel that distinguishing between 1 and 2 is more important than between 1 and 3. While None is a keyword, seeing it appear in the same color as is and other keywords feels odd.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
