In Python 3 one can say

Since the bytes type is actually a list of integers, I would have
expected this to have huh being a bytestring with one element -- the
integer 5. Actually, what you get is:
--> huh
b'\x00\x00\x00\x00\x00'
or five null bytes. Note that this is an immutable type, so you cannot
go in later and say
--> huh[3] = 9
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'bytes' object does not support item assignment
So, out of curiosity, does anyone actually use this, um, feature?
I suppose it follows the example of 'list' and 'tuple' in accepting an
iterable.
Producing a bytestring of zero bytes might have its uses, but because
Python lets me do coding at a high level (lists, dicts, etc), I've
never used that feature.
BTW, help(bytes) doesn't seem to mention it!
