simple string search and replace

[Kun]

hey guys, here's my code,

senders = [('460 (BODY[HEADER.FIELDS (FROM)] {46}', 'From: Friend
<anon@anon.whar ton.com>\r\n\r\ n'), ')', ('462 (BODY[HEADER.FIELDS
(FROM)] {37}', 'From: Kun <neurogasm@gmai l.com>\r\n\r\n' ), ')']
print senders
parsed_senders = []
sender = ""
for item in senders:
if isinstance(item ,tuple):
item= ''.join(item)
if item==')':
parsed_senders. append(sender[sender.find('<' )+1:].strip())
sender = ""
else:
sender+=item
print parsed_senders




wondering if anyone knows how i can remove the '>'s from the list, which
outputs to something like ['anon@anon.whar ton.com>', 'neurogasm@gmai l.com>']

Re: simple string search and replace

Generally, to remove a substring (like ">") from a string you can use
the replace method (that returns a new string):
[color=blue][color=green][color=darkred]
>>> s = "...anon.wharto n.com>..."
>>> s.replace(">", "")[/color][/color][/color]
'...anon.wharto n.com...'

You can use it with something like:
print [s.replace(">", "") for s in parsed_senders]

or you can put the replace() somewhere in the main loop.

Probably to solve your problem there are other solutions, like using a
RE to find email addresses inside the string...

Where you append to parsed_senders, replace

sender[sender.find('<' )+1:]

with

sender[sender.find('<' )+1:-1]

and that will use a string one shorter, omitting the ">" character.
