Below is my approach which I am sure is wrong somewhere and it doesn't work the way expected, the append doesn't do anything in my code nor does it returns any traceback all i see is a empty list printed at the end, I am using win10 x64 python 3.x atom-editor. Please take a look if you can tell me what am I doing wrong here. I want to check each list word by word if the word is not repeated in the same list it should be appended to a 'newlist'. Thanks in advance

handle = open('file.txt')
newlist = list()
for line in handle:
    #line.rstrip()
    linewords = line.split()
    print(linewords)

for word in linewords:
    newlist.append(word)
    if word not in linewords:
        continue
    


print('new: ',newlist)
