The main content of this article is to explain "what are the points for attention in the use of python instance methods", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn what to pay attention to in the use of python instance methods.

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 invocation method getMin.fun (instance, int_arr, n) # instance calling class method instance.class_fun () # class calling class method getMin.class_fun () so far I believe that you have a deeper understanding of "what is the use of the python instance method?" you might as well do it in practice.
