I am getting error as follows, I have added two underscore also don't knwo where I am getting this wrong

Answer 1

you are using a lower-case s when creating the instance

Answer 2

It looks like you're using the wrong case. You want Student , not student .

Answer 3

Resolved this error, the error was associated to case sensitivity. Student call should use Student(argument_1,argument_2) used student.
