I suppose you could use a loop with calls to raw_input() and
exec(), like:
...stuff...
while 1:
    cmd = raw_input("cmd: ")
    if not cmd:
        break
    exec(cmd)
...more stuff...

which results in something like

>>> def func():
...     print "Hi!"
... 
>>> var = 1
>>> while 1:
...     cmd = raw_input("cmd: ")
...     if not cmd:
...         break
...     exec(cmd)
... 
cmd: func()
Hi!
cmd: var = 2
cmd: 
>>> var
2

This only works with one-liners though.
