it does not work. I want to split data as in code in lines attribute.

class movie_analyzer:def __init__(self,s):for c in punctuation:import removiefile = open(s, encoding = "latin-1")movielist = []movies = moviefile.readlines()def lines(movies):for movie in movies:if len(movie.strip().split("::")) == 4:a = movie.strip().split("::")movielist.append(a)return(movielist)movie = movie_analyzer("movies-modified.dat")movie.lines

It returns that:

You can use @property decorator to be able to access the result of the method as a property. See this very simple example of how this decorator might be used:

import randomclass Randomizer:def __init__(self, lower, upper):self.lower = lowerself.upper = upper@propertydef rand_num(self):return random.randint(self.lower, self.upper)

Then, you can access it like so:

>>> randomizer = Randomizer(0, 10)
>>> randomizer.rand_num
5
>>> randomizer.rand_num
7
>>> randomizer.rand_num
3

Obviously, this is a useless example; however, you can take this logic and apply it to your situation.

Also, one more thing: you are not passing self to lines. You pass movies, which is unneeded because you can just access it using self.movies. However, if you want to access those variables using self you have to set (in your __init__ method):

self.movielist = []
self.movies = moviefile.readlines()
