__init__ method
The __init__ method is used to initialize the object’s state and contains statements that are executed at the time of object creation.
Example:
class Details:
def __init__(self, animal, group):
self.animal = animal
self.group = group
obj1 = Details("Crab", "Crustaceans")
print(obj1.animal, "belongs to the", obj1.group, "group.")Output:
Crab belongs to the Crustaceans group.
We can also modify and delete objects and their properties:
Example:
class Details:
def __init__(self, animal, group):
self.animal = animal
self.group = group
obj1 = Details("Crab", "Crustaceans")
obj1.animal = "Shrimp" # Modify object property
print(obj1.animal, "belongs to the", obj1.group, "group.")Output:
Shrimp belongs to the Crustaceans group.
Example:
class Details:
def __init__(self, animal, group):
self.animal = animal
self.group = group
obj1 = Details("Crab", "Crustaceans")
del obj1 # delete object entirely
print(obj1.animal, "belongs to the", obj1.group, "group.")Output:
Traceback (most recent call last):
