Haven't tried running this, but should give you an idea of how the
equivalent would work in Python...
import re, sys
server_totals = {}
error_totals = {}
for line in sys.stdin:
line = line.strip()
match = re.match( """
\w+
\s+
\d+
\s+
(\w+)
\s+
(\w+)""", re.X )
if match:
server, error = match.group(1), match.group(2)
server_totals[server] = server_totals.get( server, 0) + 1
error_totals[error] = error_totals.get( server, 0) + 1
HTH,
Mike
