I am very new to python so I'll apologize up front if this is some
boneheaded thing. I am using python and pyserial to talk to an embedded
pic processor in a piece of scientific equipment. I sometimes find the
when I construct the bytes object to write it adds an extra f to the
first byte.
For example if I have b'\x03\x66\x02\x01\xaa\xbb' it evaluates
to b'\x03f\x02\x01\xaa\xbb', which doesn't even seem valid.
Can anyone shine some light this?
>>> b'\x66' == b'f'
True
Python always prints a bytestring the same way. It doesn't 'remember'
how it was originally created.
Another example:
>>> b'\x68\x65\x6c\x6c\x6f\x20\x77\x6f\x72\x6c\x64'
b'hello world'
