In Python 2.x an unprefixed string literal produces a byte string.
In Python 3.x an unprefixed string literal produces a textual string.
To produce a byte string in both a b prefix is needed, e.g. b'foo'.
Since I believe Hammer works predominantly with byte strings I have used
b prefixes throughout.
In Python 3.x
- int and long types are unified. The unified type is called int.
- the text string type (unicode) is renamed to str.
- the byte string type (str) is renamed to bytes.
- chr returns a text string (i.e. str)
- xrange is renamed to range.
- dict.has_key() is removed
