When it's done loading (which in many cases happens almost immediately),
the prompt should appear. Are you seeing the prompt before the file is
There is no value printed because generic statements in Python don't
have values; it's actually a special case in Python that allows the
value of a simple expression to be printed in the interactive shell. I
suspect you're thinking of lisp / scheme and similar languages here
where everything can evaluate to a value. I dimly recall that there was
an explicit design decision when Python was developed not to do this.
