Your best bet would be to use "pexpect" module. Code may look something
like:

child = pexpect.spawn ('ftp ftp.site.com')
child.expect ('Name .*: ')
child.sendline ('username')
child.expect ('Password:')
child.sendline ('password')
child.expect ('ftp> ')
child.sendline ('
then you are using a regex expression that is a wildcard match, and
that is non-deterministic.

Has anyone else felt a desire for a 'nochange' value
resembling the 'Z'-state of a electronic tri-state output?
var1 = 17
var1 = func1() # func1() returns 'nochange' this time
print var1 # prints 17
It would be equivalent to:
var1 = 17
var2, bool1 = func1()
if bool1:
var1 = var2
Thanks for the suggestions, although I'll probably continue to use:
var1 = 17
var1 = func1(var1)
print var1
and have func1 return the input value if no change is required.
It's *almost* as nice as if there was a Nochange value available..

Traditionally, one part of the expression has to be a float for the
result to be a float (this is a holdover from C). So 100/3.0 will give
you the result you want. Alternatively, you can put "from __future__

a float.
