I was totally thinking mathwise

Started with C, so i know the Bitwise Operators, can't fool me 😎

Fun fact: the boolean equivalent of a bitwise XOR operator is the inequality operator != . This can be used, for example, to check whether two numbers are both negative (same sign), both positive (same sign), or one is positive while the other is negative (different signs): if (a # one is positive and one is negative (different signs) else: # both positive/both negative (same sign) This is also how the bitwise operation works on individual bits, which can only be 1 (True) or 0 (False), so if they're the same, you get 0 (False) as the output, else you get 1 (True). It follows that if ^ is for bitwise XOR, and != is the boolean equivalent, then == is the boolean opposite, which means ~(a ^ b) is the bitwise opposite (only selects the bits that are equivalent): ~(0b00000010 ^ 0b00000100) → ~(0b00000110) → 0b11111001 a&b - selects bits that are set in both a and b ~(a&b) - selects bits that are NOT set in a or NOT set in b or NOT set in both a and b a|b - selects bits that are set in a or set in b or set in both a and b ~(a|b) - selects bits that are NOT set in both a and b a^b - selects bits that are NOT equal in a and b, i.e. set in a or set in b, but NOT set in both a and b ~(a^b) - selects bits that are equal in a and b, i.e. NOT set in a and NOT set in b, or set in both a and b The only potential problem with ~ is the fact that it will flip hidden leading 0s to leading 1s, which results in a negative value, so beware!

I LEARNED SOMETHING NEW!

Dude that's crazy I have been studying python for a short while I plan on making it my career I actually did this one correctly

even though i know the answer to this my math brain always tells me that it is an exponent

Thank you for the useful information

No shit python is dumb as fuck, next they'll change the + signal to mean a hashmap

How I managed to forget the bitwise XOR operand? I thought since this is a quiz question about Python, there must be something about "pythoning" features. It ends up about simple logic in any programming language

I believe XOR is pronounced "ex or" as in 'exclusive or'.

XORing any value by itself is 0 btw so it’s not really “in our case” like he said it’s just always like that

I confused ^ with / and still got it right

Somehow even though I knew that the Python operator for raising a number by a power is double star (**). I didn't notice the mistake until it was shown.

mistook that for AND operation

Woow, well this was something that I didn’t know about

I've been seeing these bitwise operators pop up and while I understand the general concept that these compare the bits, I suppose I'm just not understanding why we would want to do this. Can you explain the application for these bitwise operators?

Ever wondered for any case we need a an array of bool type just to store 1 and 0. a single variable is 4 bytes meaning '32' bits only one of them.is used. Why not we use all of the 32 bits when we just want to store a single 1 and 0. well thats when we need bitwise operators to manipulate individual bits and turn them on or off get them its more space efficient this way.

Bitwise xor is useful for a quick encryption, say x is plain text and k is our key. If I showed you x^k, you wouldn’t be able to know what x was - there’s no way to undo a bitwise xor unless you knew what k was, because (x^k)^k=x

XOR

Xor

btw the square of (x-1) would be: (x-1)**2

Hmmm. Seems I need to take out Python for dinner more often.

Not a python dev, got it right. It's more like how well you know C/C++

If we’re gonna be 🤓 then you should also know it’s not called the power operator but the exponent(iation) operator

Python uses ** as a power operator

any way to have it print the binary results; so you can read them? For example print 22 in binary

** is the exponent operator

when would you need this operator for example?

Wouldn't have been fooled if this was any C like language, but Python likes to just do random magic to "make a programmers life easier" and randomly decides not to at other spots. Python is the only language where I can totally see this operator being used as a power operator.

That's every programming language. Also it's X Or not ZOR

Python is such a bad language. E. g. in Rust ^ is an exponential as it should be.

Im stupid, got myself to think it was (2x-1)^2 and then 5 is 101 ^ 10 = 101 ... there was no 5 and i got over confused 😂

I’m still a little confused why does it equal 0 instead of two since it comes first in this case?

Back when C was created, I'm pretty errors were not handled by error messages, but instead by returning numbers that will be displayed. A return of 0 means that the program ran successfully. I don't think you are required to return 0 though, at least not anymore, but it is still the convention. Correct me if I'm wrong.
