Just like the title. It seems to me it is needed from the source code but codes
in stdlib all doesn't do that.

This validation can be also done with the use of annotations, while I find
it super awful, I put this for one more example:
from functools import wraps
def validate(func):
@wraps(func)
def _wrap(self, *args, **kwargs):
variables = func.__annotations__.keys()
kwargs.update(z
Perhaps replace:
lines=soup.get_text()
file.write(lines)
...with something like:
text = soup.get_text()
lines = text.split('\n')
for line in lines:
if line.strip():
file.write('%s\n' % (line, ))
(untested)

Of course you can do the same without annotations, but with the
introduction of private attribute while your API it is under active
development:

def _wrap(self, *args, **kwargs):
variables = self._vars # Here

Something like the following might do the trick. As an added benefit,
it's easy to set all the defaults automatically in __init__ as well
without hand-adding "self.dopey = dopey". On the down side, in the
non-__init__ functions, you have to use kwargs["dopey"] and the like.
It also involves tackin

The "import" machinery uses locks of its own (to protect "sys.modules").
I assume that "load_module" will use those locks internally.
