Hi All,
I run into a problem. I have a string s that can be a number of
possible things. I use a regular expression code like below to match
and parse it. But it looks very ugly. Also, the strings are literally
matched twice -- once for matching and once for extraction -- which
seems to be very slow. Is there any better way to handle this?
def convert_data_item(s):
if re.match('^\$?([-+]?[0-9,]*\.?[0-9,]+)$',s):
g=re.match('^\$?([-+]?[0-9,]*\.?[0-9,]+)$',s)
v=float(g.group(1).replace(',',''))
elif re.match('^\(\$?([-+]?[0-9,]*\.?[0-9,]+)\)$',s):
g=re.match('^\(\$?([-+]?[0-9,]*\.?[0-9,]+)\)$',s)
v=-float(g.group(1).replace(',',''))
elif re.match('^\d{1,2}-\w+-\d{1,2}$',s):
v=dateutil.parser.parse(s, dayfirst=True)
elif s=='-':
v=None
else:
print "Unrecognized format %s" % s
v=s
return v
Thanks,
Geoffrey
