In this example, we use a dictionary comprehension to create a new dictionarycity_lengthswhere each key is the state, and the value is the number of cities in that state. Here is the exact output in the screenshot below: ReadPython Dictionary Count Get Length of Nested Dictionary in Python...
If you need to destructively iterate through a dictionary in Python, then .popitem() can do the trick for you: Python >>> likes = {"color": "blue", "fruit": "apple", "pet": "dog"} >>> while True: ... try: ... print(f"Dictionary length: {len(likes)}") ... item ...
The “len()” function, user-defined function, and “for” loop are used to count the number of keys in the Python dictionary. The user-defined function is also defined using “for loop” to iterate over the dictionary’s keys and return the total number of dictionaries in Python. The ...

It runs eight times because that's the point at which the dictionary resizes to hold more keys (we have eight deletion entries, so a resize is needed). This is actually an implementation detail. How deleted keys are handled and when the resize occurs might be different for different Python...
