Self in Python class is an object that represents the instance of the class. It is used to access the attributes and methods of the class. It is also used to bind the attributes with the given arguments.The __init__() method is called when the object is created. The __init__() method is used to initialize the attributes of the class.The __str__() method is used to represent the object as a string.
What does self mean in python
In Python, the word “self” is used in two different contexts. It can be used as a keyword in a method definition, or it can be used as a variable name within the body of a method. When self is used as a keyword, it refers to the instance of the class that is calling the method. When self is used as a variable name, it refers to the value of the instance variable.
The following example shows how self can be used as a keyword in a method definition:
class MyClass:
def __init__(self):
self.x = 10
def print_x(self):
print(self.x)
In the example above, self is used as a keyword in the __init__() and print_x() methods. It refers to the instance of the class that is calling the method.
How to use self in methods and functions in python
When self is used as a keyword in a method definition, it refers to the instance of the class that is calling the method. When self is used as a variable name, it refers to the value of the instance variable.
Why use self in python
The use of self makes it easy to differentiate between instance variables and local variables. It also makes it easier to share instance variables between different methods.
How do I use self in Python 3
In Python 3, the word “self” is used in two different contexts. It can be used as a keyword in a method definition, or it can be used as a variable name within the body of a method. When self is used as a keyword, it refers to the instance of the class that is calling the method. When self is used as a variable name, it refers to the value of the instance variable.
Differences between using self and other variables in Python
When self is used as a keyword in a method definition, it refers to the instance of the class that is calling the method. When self is used as a variable name, it refers to the value of the instance variable. Other variables are local variables and are not associated with any specific instance.
Conclusion
In Python, the word “self” is used in two different contexts. It can be used as a keyword in a method definition, or it can be used as a variable name within the body of a method. When self is used as a keyword, it refers to the instance of the class that is calling the method. When self is used as a variable name, it refers to the value of the instance variable. The use of self makes it easy to differentiate between instance variables and local variables. It also makes it easier to share instance variables between different methods.
