This topic comes up every other month or so in this list, so if you had taken a minute to search for "python safe eval" or a variation thereof in your favorite search engine, you'd get more than enough pointers.

Re: Modification of a urllib2 object ?

st solution is to save the request object and call urllib2.open twice. Alternatively check if ClientForm has a parse method that accepts strings instead of urllib2 requests and then read and save the html text explicitly: >>> text = urllib2.open(request).read() >>> soup = BeautifulSoup(text) >>> forms = ClientForm.ParseString(text) HTH, George -- http://mail.python.org/mailman/listinfo/python-list

Re: documentation: what is "::="?

t argument required > > What is it I'm not understanding here? > > Are "::=" and "<==>" documented anywhere in the python docs? Neither of these is a valid Python operator. '::=' is Backus-Naur Form (BNF) metasyntax [1]; it's a general syntax to express context free grammars. "<==>" typically denotes mathematical equivalence; it is used informally in the docs to express that two expression are equivalent. I can't tell why you get an error on str(sys.path); it works fine here. Something is probably wrong with your installation or locale configuration.

Re: replace mothod for only one object but not for a class

esn't work. The following works as expected: >>> class A(object): ... def foo(self): return 'Original' ... >>> a = A() >>> b = A() >>> a.foo() 'Original' >>> b.foo() 'Original' >>> b.foo = lambda: 'Modified' >>> a.foo() 'Original' >>> b.foo() 'Modified' HTH, George -- http://mail.python.org/mailman/listinfo/python-list
