Article Introduction：In PHP class inheritance, when the subclass overrides the parent class constructor, if the parent class constructor defines the parameters, the subclass must explicitly pass these necessary parameters to the parent class through parent::__construct() . Ignoring this step will result in a runtime error because the parent class cannot receive the parameters required for its initialization, affecting the correct construction and functionality of the object.

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.
