How to Initialize Class Variables? The Purpose of Init Method in Python

The init method is like a constructor in Java. But the usage is different in Python. Here's the best example to write Class in Python using init method. 

The init executes by default and it will initialize all the variable. The dog_1 is an instantiation of dog class. When you print the dog_1, it prints as "I am in the init method", which is from the "init" method.


How to use init method


The self means this class. It is mandatory. Not only self, but you can also give any name in that place. Instead of "self" you can give as "This_is_Python_Self". It also will work.

How to use init method

class dog:

   def __init__(self):
         print("I am in init method")


Now, instantiating the class


dog_1=dog()
print(dog_1)


The output from the above display is as below:


I am in init method

<__main__.dog object at 0x7fe7b5875be0>
