What should be the value of 0^0 in python programming? I am getting 0 which should be 1. Please clarify.

Answer 1

^ is the bitwise XOR operator in Python, so if you did print(0^0), you should get 0.

Answer 2

Hello Shaktiyavesh

I think you did something wrong.

print(0**0)
output: 1

Which is correct because n^0 is always 1. So 0^0 is also 1.

Answer 3

Thank you Denise Roßberg , Bahha🐧 and Kishalaya Saha. Actually I was mistakenly edited XOR operation. Thanks once again.

Answer 4

https://en.m.wikipedia.org/wiki/Zero_to_the_power_of_zero

"In algebra and combinatorics, the generally agreed upon value is 0^0 = 1, whereas in mathematical analysis, the expression is sometimes left undefined."

Answer 5

Because in python ^ is a bitwise or. And if you want to take power use ** as 2**2=4 , 0**0=1

Answer 6

what did you use?
print(pow(0,0)) = 1

Answer 7

Denise Roßberg But 0^n is always 0 😉

Actually 0^0 is undefined in maths.

Answer 8

Russ

Thank you. You are right.

Answer 9

Tibor Santa Didn't realise that, thanks!

Answer 10

ThanksTibor Santa .

Answer 11

Python does not recognize ^ as exponential, you need to use **.

Answer 12

Bahha🐧 So it's like 0 raised to 0 then?

Answer 13

Dear mr. Russ .
You are right as 0^0 is undefined. But in calculator, it takes 1. I wanted to check either of this Or to get some error messages. To get it undefined we may required some more deliberation. Thanks

Answer 14

Shaktiyavesh Sure, I was careful to mention "in maths" as that (rightly or wrongly) is a slightly different matter to programming. Unsure as to why Python would return 1 and not an error.

Answer 15

ThanksDr. Exceptional

Hi Silver
Pls refer this:

Answer 17

What is the binary value of 0? It is 0000. So therefore
0000 ^
0000
--------
0000

Answer 18

Epsilon ︻╦̵̵͇̿̿̿̿╤── it's not about the value of 0 in binary, it's just a mathematical convenience, which is not agreed upon by everyone.
read the Wikipedia link above.

Answer 19

Yes i would also like to know

Answer 20

Why should it be one it is simple the value is going to be 0
