Is it possible to delete the last byte of a bytes in python?

Question

For some reason, I have to remove the last byte of a bytes. For example,

teststr = b'\x01\x02\x03'

In my case, I have to remove the last byte \x03. I know the strip can do in the python string case, but it doesn't work in the bytes case.

Is there a way to do this? Any information is appreciated.

Answer 1

You can use slicing:

teststr[:-1]

is equal to:

b'\x01\x02'
