paul j3 added the comment:
An alternative would be to wrap a non-identifier name in 'repr()':
def repr1(self):
def fmt_name(name):
if name.isidentifier():
return name
else:
return repr(name)
type_name = type(self).__name__
arg_strings = []
for arg in self._get_args():
arg_strings.append(repr(arg))
for name, value in self._get_kwargs():
arg_strings.append('%s=%r' % (fmt_name(name), value))
return '%s(%s)' % (type_name, ', '.join(arg_strings))
This would produce lines like:
Namespace(baz='one', 'foo bar'='test', 'x __y'='other')
Namespace(a=1, b=2, 'double " quote'='"', "single ' quote "="'")
Namespace(')'=3, a=1)
Namespace(a=1, 'b=2), Namespace(c'=3)
With names that are deliberately messy, it is hard to say which is clearer.
