First, we will iterate over all the items (key-value pairs) of dictionary by applying a for loop over the sequence returned by items () function. You can't unpack with k, v because there is only item each time in the for loop. A generator expression is an expression that returns an iterator. However that might be a premature optimization. dt [key] ). On the other hand, values can be of any Python type, whether they are hashable or not. That is, if you modify any of them (k or v) directly inside the loop, then what really happens is that youll lose the reference to the relevant dictionary component without changing anything in the dictionary. ; In Python dictionary, the dict.items() method is used to display a list of dictionary elements . In Python 3.5, dictionaries are still unordered, but this time, randomized data structures. No, you don't, you have a collection of dictionaries. 2. rev2023.3.1.43269.
