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! ^_^

    Careful about “is” and “is not”
    These compare identity of objects, which in CPython usually checks if objects are at the same memory address.

    This works for some objects like True, False, None and small integer numbers, since they are created as unique objects when the interpreter starts.

    Usually you would use == or != for these types of comparison. See below an example where “is” fails comparing two identical float numbers.
