Thank you for your hard work on this project! 😊 While your implementation is on the right track, there are a few critical issues that need to be addressed before we can approve the pull request:
-
Skills Initialization: In the child classes, the
skillsattribute is directly assigned, which overrides the parent'sskillsattribute. Instead, use theextend()method or+=operator to add skills to the existing list. This ensures that the skills from the parent class are preserved and extended appropriately. -
FullStackDeveloper Skills: Creating new instances of
BackendDeveloperandFrontendDeveloperto access their skills is inefficient. You should directly extend theskillslist of theFullStackDeveloperinstance using theextend()method or+=operator. This will make your code cleaner and more efficient. -
Method Overrides and Multiple Inheritance: The
FullStackDeveloperclass manually calls the__init__methods of both parent classes. This approach can lead to unexpected behavior. Instead, usesuper().__init__(name)to manage multiple inheritance effectively. This ensures that the constructor ofSoftwareEngineeris called only once, avoiding potential issues with attribute initialization.
Please address these issues to ensure the code meets the core requirements and functions correctly. Once these changes are made, your code will be in great shape! Keep up the good work, and don't hesitate to reach out if you have any questions. 🚀

The constructor of FullStackDeveloper calls both BackendDeveloper.__init__ and FrontendDeveloper.__init__ directly. This is not the correct way to handle multiple inheritance in Python. Instead, you should use super().__init__(name) to ensure that the constructor of SoftwareEngineer is called only once, avoiding potential issues with attribute initialization.

Creating new instances of BackendDeveloper and FrontendDeveloper just to access their skills is inefficient and incorrect. Instead, you should directly use self.skills from the parent classes after calling super().__init__(name). This will automatically initialize the skills list correctly.

Great job on implementing the class hierarchy for different types of software engineers! 🎉 Your code meets the task requirements and constraints, and you've successfully created a structure that includes FrontendDeveloper, BackendDeveloper, AndroidDeveloper, and FullStackDeveloper classes. Each class extends the SoftwareEngineer base class and adds specific skills and methods, which is fantastic.
However, there's a critical issue with the FullStackDeveloper class due to the use of multiple inheritance. The super().__init__(name) call in your FullStackDeveloper class only initializes the BackendDeveloper part, leaving out the skills from FrontendDeveloper. To fix this, you should explicitly call the __init__ methods of both parent classes to ensure all skills are initialized correctly.
Remember, addressing these issues will help you avoid similar problems in the future and improve your coding skills. Keep up the great work, and don't hesitate to learn from these experiences! 🚀

The FullStackDeveloper class uses multiple inheritance, inheriting from both BackendDeveloper and FrontendDeveloper. The super().__init__(name) call in line 42 will only initialize the BackendDeveloper part of the FullStackDeveloper due to Python's method resolution order (MRO). This means that the skills from FrontendDeveloper will not be initialized. You should explicitly call the __init__ methods of both parent classes to ensure all skills are initialized correctly.
