# About class flow:


# 1. class define
#     a. arguments define 
#     b. define methods/function 
        # 1step define 
        #     a kya argument pass kar reaha hai 
        #         1 kitne argument pass 
        #             a. single, multipal, multipal arg as single argumen recive using * **
        #     b. function body logic 
        # 2step call fucntion 
        #     a. value pass karna 
        #     b. responce recive 
    # c. class object arguments
    #     a. __init__() ke thourgh 


# 2. class ka object 



# Python Classes and Objects

# class name me first character capital hoga

# ye class ko define kiya gaya hai
class MyFirstClass:
    print('\nHello my first class')

    def myFirstMethod():
        print('\nHello my first method.')
    
    def myFirstMethod1(a, b):
        return a*b
        # print('\nHello my first method.')

# class ka object bana rahe hai
# obj = new ClassName();

# myFirstObject objet ke thorught hum class ko access kar sakte hain.
# Matlab ki hum class ke variables aur mehtods ko call kar sakte hai.
# myFirstObject = MyFirstClass
# myFirstObject.myFirstMethod()

# result = myFirstObject.myFirstMethod1(100, 10)
# print('\nResult: ', result)
# myFirstObject.myFirstMethod()


# Python is an object oriented programming language.
# Almost everything in Python is an object, with its properties and methods.
# A Class is like an object constructor, or a "blueprint" for creating objects.


# Create a Class
# To create a class, use the keyword class:

# School name ki class hai jisme koi bhi student aa raha hai to hum check karenge ki wo student school me padhta hai ya nahi then hum usko entry denge.

class School:
    # define method to show message to student when wants to enter in shcool.
    def entry_pass():
        message = '''
        ----------------------------
            Hello Student
        ----------------------------
        What is your roll number ?
        ----------------------------
        '''
        print(message)

        existing_roll_number = [1,2,3,4,5,6,7,8,9,100]
        
        # Student roll number input
        roll_number = input('\nEnter your roll number: ')
        # Condtion to veryfy student
        # print(int(roll_number) in existing_roll_number)
        # print(existing_roll_number.index(int(roll_number)))
        
        if int(roll_number) in existing_roll_number:
            print('\nWelcome')
        elif int(roll_number) not in existing_roll_number:
            print('\nNo entry')
        else:
            print('\nWrong roll number.')
            
# School.entry_pass()

class SumUsingConstruct():

    # define constructer to pass class properties to mehtos.
    def __init__(self, a, b):
        # super().__init__()
        self.a = a
        self.b = b

    def sum_numbers(self):
        result = self.a + self.b 
        print('\nResult: ', result, personalVar)

# Create Object
# sumOBJ = SumUsingConstruct(10, 50)
# sumOBJ.sum_numbers('Aur mazza aya')

# Now we can use the class named MyClass to create objects:

# Creata a method which accepts multipal values which method can't control.
def reciveMultipalValues(*values):
    print('\nAll accepted values: ', values, '\n')

reciveMultipalValues(1,2,3,4,5,6,7,8,9)

# Convert the function into class
class ReciveMultipalValues:

    def __init__(self, *values):
        self.values = values

    def reciveMultipalValues(self):
        print('\nAll accepted values in class via cunstructer: ', self.values, '\n')

reciveOBJ = ReciveMultipalValues(1,2,3,4,5,6,7,8,9)
del reciveOBJ
reciveOBJ.reciveMultipalValues()

# The __init__() Function
# All classes have a function called __init__(), which is always executed when the class is being initiated.
# Use the __init__() function to assign values to object properties, or other operations that are necessary to do when the object is being created:


# Object Methods


# The self Parameter


# Modify Object Properties


# Delete Object Properties: del

# Delete Objects


# The pass Statement
