Note that ">>>" is commonly used in docstrings to implement doctests. That 
is, it should represent the beginning of a line (or more) of executable 
Python code, followed by the expected output for that code.

Example:

     def add(x,y):
         """Add two numbers.

         >>> 1+1
         2
         >>> add(1,1)
         2
         >>> add(1,1) == 1+1
         True
         """
         return x+y
