encode and decode should definitely work, I did the same tests as manjesh23:

>>> int(0).to_bytes(1, 'big')  # Creating a null byte (I don't know how yours is created in the first place)
b'\x00'

>>> test = int(0).to_bytes(1, 'big').decode('utf-8') + 'hello'  # Storing it as a string

>>> test
'\x00hello'

>>> print(test)
hello

>>> test.lstrip('\x00')
'hello'

>>> print(test.lstrip('\x00'))
hello

If it still doesn't work, we're missing some extra information I think
