Re: PyArg_ParseTupleAndKeywords in Python3.1

I think that "C" encoding is what I need, however I run into an odd problem. If I use the following C code static PyObject* foo(PyObject *self, PyObject *args, PyObject *kwrds) { char a, b; char *kwlist[] = {"a", "b", NULL}; if (!PyArg_ParseTupleAndKeywords(args, kwrds, "|CC", kwlist, &a, &b

How to prevent re.split() from removing part of string

I am using re.split to... well, split a string into sections. I want to split when, following a new line, there are 4 or fewer spaces. The pattern I use is: sections = re.split('\n\s{,4}[^\s]', lineoftext) This splits appropriately but I lose the character matched by [^s]. I know I can

Is there a specific library used for displaying up to date consoles in the same way top behaves? From the last time a similar question was asked[1]: You might look at the sourcecode for "iotop"[2] which would make a good example (it's a "top"-like program written in Python, used for monitorin
