# 49. Scope In Python p2

"""
# If you operate with the same variable name inside and outside of a function, Python will treat
  them as two separate variables, one available in the global scope (outside the function) and
  one available in the local scope (inside the function).

# If you need to create a global variable, but are stuck in the local scope, you can use
    the global keyword. The global keyword makes the variable global.
