What is a constructor used for?

A constructor is a special kind of method that Python calls when it instantiates an object using the definitions found in your class . Python relies on the constructor to perform tasks such as initializing (assigning values to) any instance variables that the object will need when it starts.16 Eki 2019

The constructor is a method that is called when an object is created . This method is defined in the class and can be used to initialize basic variables. If you create four objects, the class constructor is called four times. Every class has a constructor, but its not required to explicitly define it.

Constructor is used to initializing objects of a class and allocate appropriate memory to objects . That is, it is used to initialize the instance variables of a class with a different set of values but it is not necessary to initialize.
