1. An instance method is a method that belongs to an instance object. When defining an instance method, the first parameter must be self. Self refers to the current instance object.

2. The instance method is called, and the value is not needed and cannot be passed to self. Self is automatically passed parameters by the interpreter.

Example

Class getMin (): # instance method def fun (self, arr) N): print (arr [n-1]) # method @ classmethod def class_fun (cls): print ("this is class function") if _ _ name__ = "_ _ main__": arr = input (). Strip (). Split (") int_arr = [] for item in arr: int_arr.append (int (item) n = int (input ( ) instance = getMin () # call the instance method instance.fun (int_arr) with an instance N) # using class call method getMin.fun (instance, int_arr, n) # instance calling class method instance.class_fun () # class calling class method getMin.class_fun () about what to pay attention to when using python Thank you for your reading.
