Except when the comma *doesn't* make the tuple:

FWIW, there's ast.literal_eval which is safe and there's no reason to
avoid it. You'll still have to deal with the fact that a single string

As searching for the '$' sign doesn't work well in the help files,
I can not find out, where is the '$' sign used for.
If I try to use it in names,
I get a compiler error,
so it probably has some special meaning.

There's derivate function in Python diff,

it also detects rising edges.

Well, you could always try downloading and installing python:
