# Play around with these George Boole Logic
# Python program examples to gain a much
# broader perspective of what logic truly means
# in computer programming. With Boolean Logic
# a computer can make decisions according to
# data input, via user input data. However, logical
# operators such as '==', '!=', '>', '<', '>=', '<=' work
# in conjunction with for-loops and while-loops.
# With the help of the 'if', 'elif' and 'else' statements
# this can be achieved with ease.
