[PYTHON] Remove duplicate from array

[Keilun]

You can use the python sets module. Those are essentially unordered collections that enforce uniqueness among its members.

Eg.

# DISCLAIMER: Not actually tested code
import sets
array = ['blue','red','red','green']
uniquearray = sets.Set(array)


Should result in what you want. For more info:

sets are builtin now Keilun...

array = list(set(array))However, this is a very interesting blog post on the whole subject:

Ah right. I'm on an old version of python for my current project. :) That link is news to me! Nice find. Thanks!

Thank you both for your answers, intersting reading.
@NaughtyNathan : you add the list function to reconvert the array from set to list ?
Thx again

[NaughtyNathan]

Yes Lc, that's exactly right. of course you can omit this step, but you started with a list, and if you aren't constructing or adding anything else onto it it makes sense to end up with a list as you can do a lot more stuff to/with a list than you can to a set.

You can also use a dictionary:
listOfLights = ['keyLight', 'rimLight', 'backLight', 'fillLight', 'rimLight']
listOfLights
listOfLights = dict.fromkeys(listOfLights) #Convert to a dictionary
listOfLights # Now a dictionary
listOfLights = listOfLights.keys() # Convert back to a list
listOfLights
