However, I do want to mention that based upon the feedback for 3.0a1, we've decided to make the 'bytes' type immutable, and create a separate mutable bytes type, 'bytearray'. These two types are mutually compatible, but in the majority of cases you'll be using bytes, not bytearray.

Omlouvám se za omyl s bytes, vycházel jsem z Pythonu 3.0a1, kde podle tohoto http://www.artima.com/weblogs/viewpost.jsp?thread=220341 byly bytes ještě mutable.
