To iterate through a list in Python, the most straightforward method is using aforloop. The syntax is simple:for item in list_name:, whereitemrepresents each element in the list, andlist_nameis the list you’re iterating over. For example, if you have a list of city names likecities ...
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 ...
