i`m trying to learn classes, and something is holding em back, i get

"NameError: global name 'self' is not defined"

the same happens to each class field. can you help me find what am i doing wrong thank you

Code:

class Assignment:
    def __init__(self, name, discription, deadline, grade, studentID):
        self.name = name
        self.studentID = studentID
        self.description = discription
        self.deadline = deadline
        self.grade = grade

    def __str__(self):
        return "studentID:" + self.studentID + "assignment name:" + self.name +" description:" + self.description + " deadline:" + self.deadline + " grade:" + self.grade

    def validation(self):
        errors= []
        if self.studendID == "":
            errors.append("No existing student ID.")  
        if self.description == "":
            errors.append("No existing description.")
        if self.deadline == "":
            errors.append("No existing deadline.")      
        if self.deadline == "":
            errors.append("No existing deadline.")    
        return errors

    @staticmethod
    def dummyAssignments():
        ret = []
        for studentID in range(100, 121):
            print "sda"
            a = Assignment(self, name, discription, deadline, grade, studentID)
            ret.append(a)            
        return ret   

def testAssigment():
    a = Assignment("","","","","")
    print a



testAssigment()   
print Assignment.dummyAssignments()

Answer 1

You don’t need to pass self when instantiating your class.

Assignment(self, name, discription, deadline, grade, studentID)

should be

Assignment(name, discription, deadline, grade, studentID)

The error is letting you know you are trying to use a var self that is not defined in either local or global scope.
