Combined with strong public opinion, this has led some governments to regulate broadband Internet services as a public utility, similar to the way electricity, gas, and the water supply are regulated, along with limiting providers and regulating the options those providers can offer. Research suggests that a combination of policy instruments will help realize the range of valued political and economic objectives central to the network neutrality debate. Without net neutrality, ISPs can slow down the websites or services of small businesses that can't afford to pay for the so-called fast lanes. Net neutrality means that no one with more money receives special treatment. Opt-in/opt-out services exist on the end user side, and filtering can be done on a local basis, as in the filtration of sensitive material for minors. Net neutrality does not block all abilities that Internet service providers have to impact their customers' services. Net neutrality regulations may be referred to as 'common carrier' regulations. The term was coined by Columbia University media law professor Tim Wu in 2003, as an extension of the longstanding concept of a common carrier, which was used to describe the role of telephone systems. Without net neutrality, ISPs may prioritize certain types of traffic, meter others, or potentially block traffic from specific services, while charging consumers for various tiers of service. With net neutrality, ISPs may not intentionally block, slow down, or charge money for specific online content. But it is shown here to draw a parallel to the duplicate count example.Network neutrality, most commonly called net neutrality, is the principle that Internet service providers (ISPs) must treat all Internet communications equally, and not discriminate or charge differently based on user, content, website, platform, application, type of equipment, source address, destination address, or method of communication.

Note: For creating unique counts, many of the other answers provide easier and more readable code compared to the groupby solution. If unique group counts are desired, just sort the input list: counts = This can be a benefit sometimes if the groups should in fact be separate. This happens because the input list L was not sorted. Notice how it combined the first three a's as the first group, while other groups of a are present further down the list. L = # Input listД¬ounts = # Create value-count pairs as list of tuples With 'duplicate' counts from itertools import groupby Using list comprehension - Duration: 33.0Д¬ount of all elements with oupby()ДЄntoher possiblity for getting the count of all elements in the list could be by means of oupby(). You can add or subtract with iterables from your counter: > c.update(list('bbb'))ДЄnd you can do multi-set operations with the counter as well: > c2 = Counter(list('aabbxyz'))Д¬ounter( They are basically like sets that allow redundant elements into them. Usage: > from collections import CounterД¬ounters are based on Python dictionaries, their keys are the elements, so the keys need to be hashable. You can dump any iterable into a Counter, not just a list, and the Counter will retain a data structure of the counts of the elements. Tuples have this method as well: > t = tuple('aabbbffffff') Here's an example list: > l = list('aaaaabbbbcccdde') Given an item, how can I count its occurrences in a list in Python? 'import random import string from collections import Counter n=1000 l=' Here is the script I used: from _future_ import print_function I tried both methods out with a few values of n and it appears that Counter is faster by a constant factor of approximately 2. I checked how much faster Counter is for tallying lists. (or similarly with a dictionary dict((x,l.count(x)) for x in set(l)))ДЄlternatively, there's the faster Counter class from the collections library Counter(l) To count the occurrences of items in l one can simply use a list comprehension and the count() method for x in set(l)] Counting the occurrences of one item in a listДЇor counting the occurrences of just one list item you can use count() > l = Д¬ounting the occurrences of all items in a list is also known as 'tallying' a list, or creating a tally counter.
