Defining a variable in a loop, or within an 'if block' doesn't change
scope, so the variables are useable in the same way as variables
outside the loop. Obviously if you define them within an if block, they
may *not* be defined, so using them could raise a NameError.

if False:
    test = 'something'
print test

All the best,
