Re: Line indexing in Python

Hey folks, Is it possible to assign a list within a nested list to a variable? Example: l = [['1', '2', '3'], ['4', '5', '6']] for i in l: if i[0][1] == '1': m = i Indeed, I generally do not understand how to assign variables within a loop! Is there an easy way to 'flatten' a nes

Sort the values of a dict

Hi all, I have a dictionary that uses dates and a tuples ad key, value pairs. I need to sort the values of the dict and insert everything in a tuple. The additional problem is that I need to sort the values looking at the i-th element of the list. I'm not that good at python (v3.1), but this is

Re: Sort the values of a dict

I'd write it as: s = sorted(d.iteritems(), key=lambda i: i[1][2]) If using python 3, it should be d.items() instead of d.iteritems(). d.iteritems() is a generator yielding tuples of (key, value) from the dictionary 'd'. lambda i: i[1][2] is the same as: def sort_(i): return i[1][2] but in-lin

Re: Sort the values of a dict

Actually, in order to use duplicate values I need something like: >>> import copy >>> d = {1:('a', 1, 12), 5:('r', 21, 10), 2:('u', 9, 8), 3:('u', 9, 8) } >>> dc = copy.deepcopy(d) >>> t = [x for x in d.values()] >>> def third(mls): ... return mls[2] ... >>> s = sorted(t, key=third) >>> pres =
