how to make a piece of code lowercase, except strings / comment ?

[Stef Mientki]

hello,

I use Python with some simplifications and a few extensions,
as a scripting language for non-programmers.

One of the simplifications is that the language should be case-insensitive.
This is done by making the code lowercase.
But now the strings in the code are also converted to lowercase.

Is there an easy way to make a piece of code lowercase,
except all string items (single / double /triple quoted and comment) ?

thanks,
Stef Mientki
