How do I debug collection errors in Python?

Debugging collection errors in Python often involves checking the type of the collection and ensuring you're using the correct methods. Can you provide more details about the error you're encountering?

I'm getting a TypeError when trying to append to a list. It says 'NoneType' object has no attribute 'append'.

This error usually occurs when the list variable is not initialized properly. Make sure you initialize your list before appending. For example, use my_list = [] before my_list.append(item).

I see! I forgot to initialize it. What if I want to merge two lists?

You can merge two lists using the + operator or the extend() method. For example, merged_list = list1 + list2 or list1.extend(list2).

Thanks! That helps a lot.
