Actually, I meant to do this:
print ''.join(' '.join('But this parrot is dead'.split()))
Which has the same effect.

Windows sockets error codes at or above 1 aren't mapped to POSIX
error codes. Instead errno is set directly from winerror. So there's
no reason to look at wi

Assuming you mean the assembler statements then it may be true.

The presence of an if statement cannot affect whether or not a continue
can work. If you give a concrete code example, somebody will be able to
identify the confusion.
If I use an if statement, I cannot use continue after I do my error
handling, so I am really trying to use the except errorname: instead of an
if statement. Therefore, I have to find the correct error name to identify
the 10057 condition to the interpreter, but thanks anyway, Andreas.

Probably not, since they aren't really Python terms, so I'll be guessing what
