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!

    Pascal uses = for comparison (and := for assignment), which confused the fuck out of me when I switched to C.

      Some people in mathematics use := to assign functions, like f(x) := x^2; then when evaluating the function you use f(2) = 4, because it can be ser as a “true” comparison

        I’ve never seen that, even in university, and it would be equally as confusing without explanation.

          I only remember two of my professors using it, and I has to ask the first one what that mean and explain to my classmates on the second one.
