It refers to the instance of the class that is calling the method.<\/p>\n\n\n\n<p>When we define a method inside a class in Python, we need to specify the <code>self<\/code> parameter as the first parameter of the method. For example:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code>class MyClass:\n    def my_method(self, arg1, arg2):\n        # do something\n<\/code><\/pre>\n\n\n\n<p>When we call the <code>my_method()<\/code> method on an instance of <code>MyClass<\/code>, Python automatically passes the instance itself as the <code>self<\/code> parameter. For example:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code>obj = MyClass()\nobj.my_method(1, 2)  # self is implicitly passed as obj\n<\/code><\/pre>\n\n\n\n<p>We can then use the <code>self<\/code> parameter inside the method to access and modify the instance variables of the calling object. For example:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code>class MyClass:\n    def __init__(self, name):\n        self.name = name\n    \n    def my_method(self, arg):\n        print(\"Hello,\", self.name)\n        self.name = arg\n        print(\"Goodbye,\", self.name)\n<\/code><\/pre>\n\n\n\n<p>In this example, we define a class <code>MyClass<\/code> with an instance variable <code>name<\/code> and a method <code>my_method()<\/code> that prints a greeting using the current value of <code>name<\/code>, and then changes the value of <code>name<\/code> to the <code>arg<\/code> parameter.<\/p>\n\n\n\n<p>When we create an instance of <code>MyClass<\/code> and call <code>my_method()<\/code>, Python automatically passes the instance as the <code>self<\/code> parameter:<\/p>\n\n\n\n<pre class=\"wp-block-preformatted\">pythonCopy code<code>obj = MyClass(\"Alice\")\nobj.my_method(\"Bob\")  # prints \"Hello, Alice\" and \"Goodbye, Bob\"\n<\/code><\/pre>\n\n\n\n<p>Overall, the <code>self<\/code> parameter is a convention in Python that allows us to refer to the instance of a class inside its methods. It is an important aspect of object-oriented programming in Python.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Apply for Python Certification!<\/strong><\/h3>\n\n\n\n<p><a href=\"https:\/\/www.vskills.in\/certification\/certified-python-developer\">https:\/\/www.vskills.in\/certification\/certified-python-developer<\/a><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong><a href=\"https:\/\/www.vskills.in\/certification\/tutorial\/python-developer\/\" target=\"_blank\" rel=\"noreferrer noopener\">Back to Tutorials<\/a><\/strong><\/h4>\n","protected":false},"excerpt":{"rendered":"<p>The self In Python, self is a conventionally used parameter name in instance methods of a class.
