How to get unique set of words from an array by removing duplicates using python-CodePudding

Below is the array of words I'm having

l = ['Australian Cricket Team',
     'Cricket Team Australian',
     'Won Against England',
     'Against England Team']

And I want to make it That has only unique words. Below is how I want it to be after processing

['Australian', 'Cricket' ,'Team', 'Won',  'Against', 'England']

Simply I want to have unique set of words.

You can use a loop:

l = ['Australian Criket Team', 'Cricket Team Australian', 'Won Against England', 'Against England Team']

set(w for s in l for w in s.split())

Output: {'Against', 'Australian', 'Cricket', 'Criket', 'England', 'Team', 'Won'}

Or, if order matters:

list(dict.fromkeys(w for s in l for w in s.split()))

Output: ['Australian', 'Criket', 'Team', 'Cricket', 'Won', 'Against', 'England']

functional variant

from itertools import chain
set(chain.from_iterable(map(str.split, l)))

Try this

def unique(list1):
 
    # initialize a null list
    unique_list = []
     
    # traverse for all elements
    for x in list1:
        # check if exists in unique_list or not
        if x not in unique_list:
            unique_list.append(x)
    # print list
    for x in unique_list:
        print x,
