Question

which is a valid hexadecimal number in python​

Answer 1

Answer:

Our normal counting system only uses the digits 0 through 9. But hexadecimal uses the digits 0 through F. Yes, in hexadecimal, things like A, B, C, D, E, and F are considered numbers, not letters. That means that 200 is a perfectly valid hexadecimal number just as much as 2FA is also a valid hex number.
