I read the following sentence in book "introducing python"
Python 3 strings are Unicode strings, not byte arrays. This is the single largest change from Python 2, which distinguished between normal byte strings and Unicode character strings.
I am very confused here, I tested respectively in python3 and python2
in python 3
In [12]: s = "python3"
In [13]: type(s)
Out[13]: str
In python2:
>>> s = "python2"
>>> type(s)
<type 'str'>
They are of the identical type.
How could I find the description "byte arrays" in "python2"?
