global name NAME is not defined PYTHON

I have problems with the following code, it says "NameError: global name 'Teater' is not defined" I can not solve it by myself...

teaterLista = []
lista = []
class Teater:


    def __init__(self, teaterNamn, plats, pensionar,vuxen,barn):
        self.teaterNamn = teaterNamn
        self.plats = plats
        self.pensionar = pensionar
        self.vuxen = vuxen
        self.barn = barn

    def readData():
        #x = Teater(x,teaterNamn, plats,pensionar,vuxen,barn)
        dataFile = open('c:/Teater.txt','r')
        for line in dataFile:
            if(line != '\n'):
                  temp = line.split('=',1)[1]
                  lista.append(temp.strip()) #strip tar bort radavslut

        x = Teater(x,lista[0],lista[1],lista[2],lista[3],lista[4])
    #teaterLista[0] = x
    #print(teaterLista[0])

    readData()

You call readData() during class definition. In Python a class body is executed during its definition in the contex of the class definition just as normal code would be. As the class is not completely defined at that moment, you cannot create a new instance, yet, thus get the error.

Dedent the whole definition for readData and the following line so all this is executed after the definition of the class has completed. This makes readLine a module-level function, not a class method. This is typical for a factory function.

teaterLista = []
lista = []
class Teater:

    def __init__(self, teaterNamn, plats, pensionar,vuxen,barn):
        self.teaterNamn = teaterNamn
        self.plats = plats
        self.pensionar = pensionar
        self.vuxen = vuxen
        self.barn = barn

def readData():
    #x = Teater(x,teaterNamn, plats,pensionar,vuxen,barn)
    dataFile = open('c:/Teater.txt','r')
    for line in dataFile:
        if(line != '\n'):
              temp = line.split('=',1)[1]
              lista.append(temp.strip()) #strip tar bort radavslut

    x = Teater(lista[0],lista[1],lista[2],lista[3],lista[4])
#teaterLista[0] = x
#print(teaterLista[0])

readData()

Note: x = Teater(x, ... will not work, as x is not defined for the first invocation. If you think about specifying this for the self argument: no need; this is done implicitly. You should read how classes work in the documentation/tutorial.

You have to be careful in Python to correctly indent your code, as that defines the block scope.
