What are some common mistakes in Python and C++?

In Python, common mistakes include using mutable default arguments and forgetting to use 'self' in class methods. In C++, forgetting to manage memory properly and not using the correct data types are frequent issues.

Can you explain why mutable default arguments are a problem in Python?

Sure! Mutable default arguments can lead to unexpected behavior because they retain changes between function calls. This can cause bugs that are hard to track down.

What about memory management issues in C++?

In C++, failing to free allocated memory can lead to memory leaks, while accessing freed memory can cause crashes. It's crucial to manage memory carefully.

How can I avoid these mistakes in my code?

To avoid these mistakes, always initialize your variables, use tools like linters, and practice good coding habits like code reviews.
