Update key-to-address-ecc-example.py 
If line#24 use 'wif_compressed', it will produce a wrong Key (WIF-Compressed) started with 2.

So there should be 'wif', unless :
wif_compressed_private_key = bitcoin.encode_privkey(
    bitcoin.decode_privkey(private_key, 'hex'), 'wif_compressed')
This is also right. 
However, use the 'compressed_private_key' and 'wif_compressed' is wrong.

9504d804e0 Stop using numeric_limits for the constant "255", and fix a bug. 
The bug is that `x % 255` is not quite the same thing as `x % 256`;
but `x & 255` is.

The stylistic issue is that `numeric_limits<uint8_t>::max()` is a
very verbose way of spelling `255`.

Update key-to-address-ecc-example.py 
The code is very possible to miss a leading '0'.
E.g:
Private Key (hex) is: 57c003d31cca32f79a22e70334fff37875617e89c04d2746b5efc22067ccb8fd
Before: Compressed Public Key (hex) is: 03 8f0de2360796ae0fe17f1a2b0be30af6fb45eccc4a1c7afb5ebea21d041b6e0
After: Compressed Public Key (hex) is: 03 08f0de2360796ae0fe17f1a2b0be30af6fb45eccc4a1c7afb5ebea21d041b6e0

The bug is in the pybitcointools, but it is not updated, we can only repair it ourselves.

Update hash_example.py 
As input and hash are inbuilt functions, so I'd suggest using other names for variables.
here is output from python interpreter.

>>> hash
<built-in function hash>
>>> input
<built-in function input>

`from __future__ import print_function` to bring the print function from Python 3 into Python 2.6 and 2.7.

Properly deals with comma separated values in print() function.
