Common Dictionary Methods in Python
Dictionaries have unique characteristics that set them apart from lists and tuples. They also come with their own set of methods.
Like tuples, dictionaries don't have methods like .append() or .extend() and don't support concatenation. Instead, to add or update an entry you can use dict[key] = value – this assigns the value value to the key key, creating a new pair if key doesn't exist.
