FWIW, here are three more comparative code fragments. They are
presented without judgment as an evaluation tool to let everyone form
their own opinion about the merits of each:
--- From CGIHTTPServer.py ---------------
def run_cgi(self):
"""Execute a CGI script."""
dir, rest = self.cgi_info
i = rest.rfind('?')
if i >= 0:
rest, query = rest[:i], rest[i+1:]
else:
query = ''
i = rest.find('/')
if i >= 0:
script, rest = rest[:i], rest[i:]
else:
script, rest = rest, ''
. . .
def run_cgi(self):
"""Execute a CGI script."""
dir, rest = self.cgi_info
try:
i = rest.rindex('?')
except ValueError():
query = ''
else:
rest, query = rest[:i], rest[i+1:]
try:
i = rest.index('/')
except ValueError():
script, rest = rest, ''
else:
script, rest = rest[:i], rest[i:]
. . .
--- From ConfigParser.py ---------------
optname, vi, optval = mo.group('option', 'vi', 'value')
if vi in ('=', ':') and ';' in optval:
# ';' is a comment delimiter only if it follows
# a spacing character
pos = optval.find(';')
if pos != -1 and optval[pos-1].isspace():
optval = optval[:pos]
optval = optval.strip()
. . .
optname, vi, optval = mo.group('option', 'vi', 'value')
if vi in ('=', ':') and ';' in optval:
# ';' is a comment delimiter only if it follows
# a spacing character
try:
pos = optval.index(';')
except ValueError():
pass
else:
if optval[pos-1].isspace():
optval = optval[:pos]
optval = optval.strip()
. . .
--- StringIO.py ---------------
i = self.buf.find('\n', self.pos)
if i < 0:
newpos = self.len
else:
newpos = i+1
. . .
try:
i = self.buf.find('\n', self.pos)
except ValueError():
newpos = self.len
else:
newpos = i+1
. . .
My notes so far weren't meant to judge the proposal. I'm just
suggesting that examining fragments like the ones above will help inform
the design process.
Peace,
Raymond
