How do I split and sort strings in a list using for loops in Python-CodePudding

Trying to read a file then store it in a list but not getting the desired output:

fname = input("Enter file name: ")
fh = open(fname)
lst = list()
for line in fh:
    #line = line.rstrip()
    words = line.split()
        if words not in lst:
            lst.append(words)
            
lst.sort()
print(lst)

My Output:

[['Arise', 'fair', 'sun', 'and', 'kill', 'the', 'envious', 'moon'], ['But', 'soft', 'what', 'light', 'through', 'yonder', 'window', 'breaks'], ['It', 'is', 'the', 'east', 'and', 'Juliet', 'is', 'the', 'sun'], ['Who', 'is', 'already', 'sick', 'and', 'pale', 'with', 'grief']]

Desired Output:

['Arise', 'But', 'It', 'Juliet', 'Who', 'already', 'and', 'breaks', 'east', 'envious', 'fair', 'grief', 'is', 'kill', 'light', 'moon', 'pale', 'sick', 'soft', 'sun', 'the', 'through', 'what', 'window', 'with', 'yonder']

CodePudding user response：

All you have to do is loop through all of the words in the sentence, then check if they are already in the list, then append them.

fname = input("Enter file name: ")
fh = open(fname)
lst = list()
for line in fh:
    #line = line.rstrip()
    words = line.split()
    for word in words:
       if word not in lst:
            lst.append(word)
            
lst.sort()
print(lst)
