2010-06-12 Thread Javier Montoya
Dear all, I need to generate a vector of random float numbers between [0,1] such that their sum equals 1 and that are distributed non-uniformly. Is there any python function that generates such a vector? Best wishes -- http://mail.python.org/mailman/listinfo/python-list

Dear all, I'm new to python and have been working with the numpy package. I have some numpy float arrays (obtained from np.fromfile and np.cov functions) and would like to convert them to simple python arrays. I was wondering which is the best way to do that? Is there any function to do that? Bes

Dear all, I've a list of float numbers and I would like to delete incrementally a set of elements in a given range of indexes, sth. like: for j in range(beginIndex, endIndex+1): print ("remove [%d] => val: %g" % (j, myList[j])) del myList[j] However, since I'm iterating over the same list,

Dear all, I'm a newbie in python and would be acknowledge if somebody could shed some light on associative arrays. More precisely, I would like to create a multi-dimensional associative array. I have for example a list of students which are identified uniquely by their student IDs. Additionally, f
