removing word interchanged elements of list in python

Question

I have a list with repeating values which have been interchanged. for example

dataList=["john is student", "student is john", "john student is", "john is student", "alica is student", "good weather", "weather good"]

I want to remove all these repeating values as shown:

expected output:

dataList=["john is student","john is student", "john is student","john is student","alica is student", "good weather", "good weather"]

the code which I am trying to use is:

for i in dataList:
    first=(i.split()[0]) +  i.split()[1] + i.split()[2]) in studentList
    ........

I am stuck in forming a logic. May I know how I can get my required result

Answer 1

If you consider that first occurrence is correct one that you need in the final list then you can try following:

dataList= ["john is student", 
           "student is john", 
           "john student is", 
           "alica is student", 
           "good weather", 
           "weather good",
          ]

data = {}
for words in dataList:
    data.setdefault(frozenset(words.split()), words)

dataList = data.values() 
 # dataList is you need

Edit

Since I last answer question has been updated with the requirement to keep the repetitive values.

[Answer]

dataList= ["john is student", 
           "student is john", 
           "john student is",
           "alica is student",
           "good weather", 
           "weather good",
          ]

class WordFrequence:
    def __init__(self, word, frequence=1):
        self.word = word
        self.frequence = frequence

    def as_list(self):
        return [self.word] * self.frequence

    def __repr__(self):
        return "{}({}, {})".format(self.__class__.__name__, self.word, self.frequence)    

counter = {} 
for words in dataList:
    key = frozenset(words.split())
    if key in counter:
        counter[key].frequence += 1
    else:
        counter[key] = WordFrequence(words)

dataList = [] # this is what you need
for wf in counter.values():
    dataList.extend(wf.as_list())

For long input dataList you can improve my code by replacing WordFrequence with recordclass
