Hi,
I would like to read from a pipe, parse the input and ask the user
what to do next:
message = sys.stdin.read()
# message is parsed and URLs are printed as a list to choose from...
selected_index = raw_input('Which URL to open?')
Calling raw_input() always raises in an EOFError. I tried reope
Hi,
up to now I use this code to parse date values from emails:

The curl & dig ideas were great, thanks. Turns out the machine's network was
badly configured and that's probably what was causing this problem. Curiously
firefox could browse these sites without any problem despite not having any
proxy defined and it took the command line to reveal the issue.
