I have no idea what you mean by "running python in a browser". I can 
only guess you mean as cgi or mod_python-skript?

However, maybe

if os.isatty(sys.stdout.fileno()):


works for you.

Or you could check for certain environment variables that are present 
when running as CGI or mod_python skript, but not knowing *what* you do 
can only lead to educated guesses at best.
