with it.

Not sure if I'm fully understanding the question. But one option instead of
making everything class attributes is to just define __getattr__ for when it
doesn't find an attribute.

In your __rsub__ (used when you have - ) you instead return

Notice how the final return should also be -4,95 and not the +4,95 it's

Hi,
The exact explanation of how 'and' and 'or' behave can be read here:
One can use the `dis` module and investigate the generated python
bytecode. For me, I get

thing = 123
for i in range(10):
if "hi" == str(thing):
print("found")

The bytecode is then
