This is a sample O O P project.(NOT WORKING PROPERLY)

class Student:   #Common base class for all students.
    studentcount = 0    #class variable.

    def __init__(self, rollno, name, age):   #class constructor.
        self.rollno=rollno
        self.name=name
        self.age=age
        Student.studentcount = +1

    def displayCount(self):
         print("Total students:",Student.studentcount)

    def displayStudent(self):
        print("Rollno :", self.rollno)
        print("Name:", self.name)
        print("Age:", self.age)

    st1=Student(1001," Mahi", 24)
    st2=Student(1002,"Mohan", 25)
    st3=Student(1003,"Madan",22)

    st1.displayStudent( )
    st2.displauStudent()
    st3.displayStudent()
    print("Total number of students:", Student.studentcount )

can anyone point out the error.

I can’t see any error. I think something wrong in class construction .
Following is the error message
“C:\Users\Administrator\PycharmProjects\O O P Class & Objects\venv\Scripts\python.exe” “C:/Users/Administrator/PycharmProjects/O O P Class & Objects/main.py”
Traceback (most recent call last):
File “C:/Users/Administrator/PycharmProjects/O O P Class & Objects/main.py”, line 3, in
class Student:
File “C:/Users/Administrator/PycharmProjects/O O P Class & Objects/main.py”, line 20, in Student
st1=Student(1001," Mahi", 24)
NameError: name ‘Student’ is not defined

Process finished with exit code 1
