How to give hexadecimal input to SHA256 in python 3?

Question

I'm trying to get SHA256 output for hexadecimal values but only able to give string input. The Python 3 code I use is given below

from hashlib import sha256
hash = sha256(b'0x01')
hx=hash.hexdigest()
print('hx: ', hx)

What I get

hx:  b51c80e50d664f281fedd07ba902a21caadc0c7e0b491ece679497391e9f84cf

What I expect

hx:  4bf5122f344554c53bde2ebb8cd2b7e3d1600ad631c385a5d7cce23c7785459a

The expected output is from the online tool SHA256 Online with input type as hex.

Convert the hexadecimal string to bytes using bytes.fromhex():

from hashlib import sha256
hash = sha256(bytes.fromhex('01'))
hx = hash.hexdigest()
print('hx: ', hx)
