Parameterized Constructor

- Constructor with parameters is called a parameterized constructor.

- Below classes are examples of parameterized constructors.

Parameterized Constructor:

Explanation of the Below Code:

- We create a class with the init method.

- We create a chirag-named class.

- We create a lastname1-named class variable.

- Then we define the init method with the self and lastname2 parameters, then create an instance variable using the class variable which returns the argument of the lastname2 parameter.

- Then we define a readlastname-named method with a self-parameter, we take the instance variable in the print function which returns the value of instance variable.

- Then we create an a-named instance(object) of the chirag class.

- Then we call the readlastname method using the a-named instance(object).

Access some specific info. of an object using some specific method:

Explanation of the Below Code:

- We create a class with the init method.

- We create a me-named class.

- Then we define the init method with the self, fname, lname, and age parameters, then create some instance variable for each parameters. 

- Then we define a showfname-named method with a self-parameter, we take the instance variable in the print function which returns the value of instance variable.

- Then we define a showlname-named method with a self-parameter, we take the instance variable in the print function which returns the value of instance variable.

- Then we define a showAge-named method with a self-parameter, we take the instance variable in the print function which returns the value of instance variable.

- Then we create the a1 and a2-named instances(objects) with three arguments (separate with a comma) of me class.

- Then we call the showfname method using the a1-named instance(object).

- Then we call the showlname method using the a2-named instance(object).

- Then we call the showAge method using the a2-named instance(object).
