How to get the second digit of a number or string in python?

Is there any good idea how to get the second digit of a string? For example:

aaa = 122
bbb = 333

rest = bbb-aaa 
if rest[:2] == 1: 
    do something..

Convert the integer to a string first using the built-in str() function and then slice it accordingly

So Try this:

if str(rest)[1] == '1':
    #do something example:
    print 'hi'
