Confused about logical operators (i.e. "comparison operators", or "boolean operators") in Python (lemmy.blahaj.zone)

I thought = was a mathematical operator, not a logical operator; why does Python use

>= instead of >==, or <= instead of <==, or != instead of !==?

Thanks in advance for any clarification. I would have posted this in the help forums of FreeCodeCamp, but I wasn't sure if this question was too.......unspecified(?) for that domain.

Cheers!

Edit: I think I get it now! Thanks so much to everyone for helping, and @FizzyOrange@programming.dev and @itslilith@lemmy.blahaj.zone in particular! ^_^

It does still have a traditional assignment operator. You can assign values to mutable variables.

Also I would say let-binds are still pretty much assignment; they just support destructuring. Plenty of languages support that to some extent (JavaScript for example) and you wouldn't say they don't have assignment.

I don't think it affects the ability to overload = anyway. I think there aren't any situations in Rust where it would be ambiguous which one you meant. Certainly none of the examples you gave compile with both = and ==. Maybe there's some obscure case we haven't thought of.
