Re: error estimation in a non-linear least squares fitting

Thanks Robert for your reply. I must say I am kind of disappointed if that is the only solution. I thought that such a standard problem as least squares fitting, would always give you an estimation of the error bars, without having to look up how you can convert a covariance matrix into error bars.

Why can't I assign a class method to a variable?

I'm trying to make a shortcut by doing this: t = Globals.ThisClass.ThisMethod Calling t results in an unbound method error. Is it possible to do what I want? I call this method in hundreds of locations and I'm trying to cut down on the visual clutter. Thank you! -- http://mail.python.org/ma

[APSW] SELECT COUNT(*) not succesfull?

Hello I'm trying to use the APSW package to access a SQLite database, but can't find how to check if a row exists. I just to read a tab-separated file, extract a key/value from each line, run "SELECT COUNT(*)" to check whether this tuple exists in the SQLite database, and if not, run an INSERT. T

Re: How can I handle the char immediately after its input, without waiting an endline?

Is there a way to do the opposite of tty.setraw afterwards to prevent the terminal from not displaying any characters that are typed in? Of course, this can be resolved by re-opening it, but thats not really convenient. -- http://mail.python.org/mailman/listinfo/python-list

substitution of a method by a callable object

Can I substitute a method of a class by a callable object (not a function)? I can very easy insert my function in a class as a method, but an object - can't. I have the following: class Foo(object): pass class Obj(object): def __call__(self, obj_self): print 'Obj' def func(self)
