Article Introduction：To create an instance of a class in Python, you need to call the class constructor. The specific steps are as follows: 1. Define the class and initialize the attributes using the \_\_init\_\_ method; 2. Create an object by parentheses and pass corresponding parameters; 3. Define a constructor without parameters or with default values ??to meet different initialization needs; 4. Advanced use factory methods such as class methods to provide more flexible object creation methods. For example, Person("Alice", 30) will automatically call \_\_init\_\_init\_init, while Rectangle.square(5) creates a square object through class methods.
