Deleting Repeats In A List Python

Possible Duplicates:
How do you remove duplicates from a list in Python whilst preserving order?
In Python, what is the fastest algorithm for removing duplicates from a list so that all elements are unique while preserving order?

I was wondering if there was a function which does the following:

Take a list as an argument:

list = [ 3 , 5 , 6 , 4 , 6 , 2 , 7 , 6 , 5 , 3 ]

and deletes all the repeats in the list to obtain:

list = [ 3 , 5 , 6 , 4 , 2 , 7 ]

I know you can convert it into a dictionary and use the fact that dictionaries cannot have repeats but I was wondering if there was a better way of doing it.

Thanks

Please see the Python documentation for three ways to accomplish this. The following is copied from that site. Replace the example 'mylist' with your variable name ('list').

First Example: If you don’t mind reordering the list, sort it and then scan from the end of the list, deleting duplicates as you go:

if mylist:
    mylist.sort()
    last = mylist[-1]
    for i in range(len(mylist)-2, -1, -1):
        if last == mylist[i]:
            del mylist[i]
        else:
            last = mylist[i]

Second Example: If all elements of the list may be used as dictionary keys (i.e. they are all hashable) this is often faster:

d = {}
for x in mylist:
    d[x] = 1
mylist = list(d.keys())

Third Example: In Python 2.5 and later:

mylist = list(set(mylist))
