Ron Adam:
Insted of:
def __init__(self, flags=[]):
self.flags = flags
self.numrex = re.compile(r'([\d\.]*|\D*)', re.LOCALE)
self.txtable = []
if HYPHEN_AS_SPACE in flags:
self.txtable.append(('-', ' '))
if UNDERSCORE_AS_SPACE in flags:
self.txtable.append(('_', ' '))
if PERIOD_AS_COMMAS in flags:
self.txtable.append(('.', ','))
if IGNORE_COMMAS in flags:
self.txtable.append((',', ''))
self.flags = flags
I think using a not mutable flags default is safer, this is an
alternative (NOT tested!):
numrex = re.compile(r'[\d\.]* | \D*', re.LOCALE|re.VERBOSE)
dflags = {"hyphen_as_space": ('-', ' '),
"underscore_as_space": ('_', ' '),
"period_as_commas": ('_', ' '),
"ignore_commas": (',', ''),
...
}
def __init__(self, flags=()):
self.flags = [fl.strip().lower() for fl in flags]
self.txtable = []
df = self.__class__.dflags
for flag in self.flags:
if flag in df:
self.txtable.append(df[flag])
...
This is just an idea, it surely has some problems that have to be
fixed.
