TypeError: can't concat bytes to str
How do I write this function so it can pad byte strings? chr(charcode)
creates a normal string, not a binary string.
I can figure out way for example this:
>>> b'T'+bytearray([32])
but it just don't seem right to create a list, then convert it to a byte
array and then convert it to a binary string. What am I missing?
