[Pythonmac-SIG] newbie

[Kevin Altis]

Personally, I prefer the more technically correct (and explicit)  \r\n 
line endings for web headers. In the case of this example text/plain is 
more appropriate than html as the content-type.

print "Content-type: text/plain\r\n\r\n",

Besides the excellent suggestions in Philip's email you should also 
watch out for the line endings you use in your CGI scripts. If you are 
editing in Emacs, vi, etc. from the Terminal chances are you have 
newline (\n) line endings, but if you're editing with a text editor 
from the Finder you might be surprised to find your scripts ending with 
\r (carriage return) and if you brought a script over from a Windows 
box you could have \r\n line endings. If you're using Python 2.3.x I 
would think that the universal line-endings handling would work with 
all three versions on the Mac, but there might be problems with older 
versions.
