One thing that I find easier in C compared to Python is that loops are not as expensive. And sometimes, things are easier to implement when you can think of them individually.

For example, to render characters with different styles, we can do this in C:

for (index = 0; index < SIZE; index++) {
    render_character(characters[index], styles[index]);
}

This is cheap in C. But in Python, it is expensive. So to make this fast in Python, we might want to do something like this:

for (substring, style) in split_parts(text):
    render_text(substring, style)

Assuming we can write split_parts without looping over all characters, this will perform better in Python because of fewer loop iterations.
