How would you find how many times a number is entered?

I'm wondering how you'd enter a lot of numbers and have the script print out the ones that were repeated the most. Something like this:

(numbers entered)
1,4,10,23,4,6,14,33,6,12,24,34,1,3,6,23,8,19,20,23
Print out would be:
1,4,6,23
because they are the most used, if I wanted only the highest 4 numbers used.

Output:
[1, 1, 3, 4, 4, 6, 6, 6, 8, 10, 12, 14, 19, 20, 23, 23, 23, 24, 33, 34]
(2, 1)
(1, 3)
(2, 4)
(3, 6)
(1, 8)
(1, 10)
(1, 12)
(1, 14)
(1, 19)
(1, 20)
(3, 23)
(1, 24)
(1, 33)
(1, 34)
23 6 4 1

Wow! Impressive.....thank you very much!

You're welcome. It's just a little something that I whipped up while eating my lunch.

May I get in on this thread?
I am in Python 2.3, therefore the cmp function in sort.

Thanks BV and GD. Two great coders show that there are alway many ways to skin a cat in Python. You guys rock!

1. >>> l = [1,4,10,23,4,6,14,33,6,12,24,34,1,3,6,23,8,19,20,23  ]
2. >>> cnt = [l.count(item) for item in set(l)]
3. >>> cnt
4. [2, 1, 1, 2, 3, 1, 1, 1, 1, 1, 1, 1, 3, 1]
5. >>> sorted(zip(cnt,set(l)))[-4:]
6. [(2, 1), (2, 4), (3, 6), (3, 23)]
7. >>> for i in sorted(zip(cnt,set(l)))[-4:]:
8. ...  print i[1],
9. ...
10. 1 4 6 23
11.  

I should have thought of pulling off the end of the list. Very nice.

All very nice! Question though about ghostdog74's.....I get this:

Traceback (most recent call last):
File "<pyshell#8>", line 2, in <module>
print i[l],
TypeError: tuple indices must be integers

If I change it to simply 'print i' it works but like this:
(2, 1)
(2, 4)
(3, 6)
(2, 23)

This is fine but I was just curious as to why mine wouldn't print out the same way.

... print i[1],

One is definitely an integer. You haven't included your version. Looks like you have a typo.

as barton said, its a 1, not an 'l' . As you can see the results are tuples.
