  • How can i optimize this python code

    - by RandomVector
    def maxVote(nLabels): count = {} maxList = [] maxCount = 0 for nLabel in nLabels: if nLabel in count: count[nLabel] += 1 else: count[nLabel] = 1 #Check if the count is max if count[nLabel] > maxCount: maxCount = count[nLabel] maxList = [nLabel,] elif count[nLabel]==maxCount: maxList.append(nLabel) return random.choice(maxList) nLabels contains a list of integers. The above function returns the integer with highest frequency, if more than one have same frequency then a randomly selected integer from them is returned. E.g. maxVote([1,3,4,5,5,5,3,12,11]) is 5

  • Python file - Want to change it to a function or a class

    - by curious2know
    Hello, I have a python program/file that I want to run repeatedly and calculate the averages of some variables over these runs. To do so, I thought it might be convenient to convert this program into a function or a class. One way I can think of is to add a def Main(): line at the top and indent every line manually within it. Is there an easier way? I am using pydev on eclipse. Thanks.
