Initial Comment:
Hi Python-Developers

I am new to python and maybe this was considered 
before. I think it would be VERY helpful, if one 
could use assignments as expressions as it is in C, 
e.g. in while-loops:


import mailbox

file = open('mailfile')
mbox = mailbox.PortableUnixMailbox(file)

# the following line produces
# SyntaxError: invalid syntax
while mail = mbox.next():
    # do something with this mail
    ...



Best regards

      Frank Sonnenburg

In Python 2.2, iterators solve this problem:

for mail in mbox:
  #do something

Closing this as "works for me".
