Confused about logical operators (i.e. "comparison operators", or "boolean operators") in Python
(lemmy.blahaj.zone)
Note: The attached image is a screenshot of page 31 of Dr. Charles Severance's book, Python for Everybody: Exploring Data Using Python 3 (2024-01-01 Revision).
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! ^_^
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.
