Seeing Variables

  Did you know that after your program has terminated in IDLE,
  you still can see the variables in the shell?

  For example:

  IDLE editor

a = 1   (user input)

  [F5] - run   (user input)

  IDLE shell

a   (user input)
1   (system output)

  But how to achieve the same for local variables? E.g.,

  IDLE editor

def f():      (user input)
    a = 1     (user input)

  IDLE shell

a   (user input)
NameError: name 'a' is not defined   (system output)
