My code:

class tan:
    nev = []
    tantargy = []
    osztaly = []
    oraszam = []

    def fel1(self):
        print("1.feladat")
        f = open("/home/i3hunor/Programozas/Info_erettsegi/Erettsegi/2s_2019maj-ideg/Forrasok/4_Tantargyfelosztas/beosztas.txt","r")

        for sor in f:
            tomb = sor.rstrip()

    print(self.nev,"\n",self.tantargy)

Expected output:

(self.nev) (in list or any format)

Albatrosz Aladin,Albatrosz Aladin,Albatrosz Aladin,Antilop Anett,Bagoly Barbara

(self.tantargy)

biologia, kemia, osztalyfoniku, testneveles, nemet

Is it possible to do this? What did i do wrong and why can't I use smt like tomb[1]. Sorry if my question is not understandable, i can't explain it more cause of my lack of english skills.

Are you trying to read a file with tokens separated by new-line, and put them in a list? Take a look here: https://stackoverflow.com/a/71978699/13238310

Read all the lines, then iterate on them by batch of 4, and save them in the appropriate lists

class tan:

    def __init__(self):
        self.nev = []
        self.tantargy = []
        self.osztaly = []
        self.oraszam = []

    def fel1(self):
        with open("test.txt") as f:
            lines = f.readlines()
            for i in range(0, len(lines), 4):
                n, t, os, ora = lines[i:i   4]
                self.nev.append(n.rstrip())
                self.tantargy.append(t.rstrip())
                self.osztaly.append(os.rstrip())
                self.oraszam.append(ora.rstrip())

t = tan()
t.fel1()  # load data
print(t.nev)
# ['Albatrosz Aladin', 'Albatrosz Aladin', 'Albatrosz Aladin', 'Antilop Anett', 'Bagoly Barbara']
print(t.tantargy)
# ['biologia', 'kemia', 'osztalyfonoki', 'testneveles', 'nemet']

You would need to initialize the lists, then read and append the appropriate elements to these lists.

class Tan:
    def __init__(self):
        self.nev = []
        self.tantargy = []
        self.oztaly = []
        self.oraszam = []

    def read(self):
        file = open("test.txt", "r", encoding="utf-8")

        line = file.readline().replace("\n", "")
        count = 0        

        while line != "":
            if count%4 == 0:
                self.nev.append(line)
            elif count%4 == 1:
                self.tantargy.append(line)
            elif count%4 == 2:
                self.oztaly.append(line)
            else:
                self.oraszam.append(line)
            count  = 1
            line = file.readline().replace("\n", "")

        file.close()

    def display(self):
        print(self.nev)
        print(self.tantargy)
        print(self.oztaly)
        print(self.oraszam)

tan = Tan()
tan.read()
tan.display()
