No. Sorry. Every time you run python you will get a completely new
environemnt which has no memory of what previous invocations have done. Like
this:

$ python -c "myvar = 21"

$ python -c "print myvar"
Traceback (most recent call last):
  File "<string>", line 1, in ?
NameError: name 'myvar' is not defined

That's good, b ut you are going to have to go a little further to get what
you want. Of course, IDLE and PythonWin do this already, so at least there's
a body of Python source for you to read.
