Trying to get unique words from a set of strings

[deanhystad]

You should never remove items from the thing you are iterating. Instead build a new list that has the desired characteristics.

string ='red,red,white,white,pink,blue,white,white,blue,blue,white'
wordlist = string.split(',')
print(wordlist)

# Make a list only containing unique words
uniquewords = [word for word in wordlist if wordlist.count(word) == 1]
print('Unique colors', uniquewords)

# Make a list where each word only occurs once
colors = set(wordlist)
print('Colors', colors)
