How would you iterate over the keys in a dictionary named my_dict?

Iterating over the keys in a dictionary can be accomplished in a straightforward manner. When you use the syntax "for key in my_dict:", you are directly iterating over the dictionary itself. In Python, when you loop through a dictionary, it implicitly iterates over its keys.

This means that each iteration gives you the next key from the dictionary, allowing you to access not just the keys but also their corresponding values if needed.

While the other options may represent valid approaches, they are either more verbose or not functioning as intended. For example, using "my_dict.items()" will give you both keys and values, which is useful when you want to access both simultaneously, but it is not necessary if you only need the keys. As for "for key, value in my_dict:", this assumes a tuple unpacking format but does not properly reference the dictionary’s items, leading to an error. Lastly, "for key in my_dict.keys():" is functionally equivalent to the correct choice but is unnecessarily longer, as calling the keys() method is redundant when directly iterating over the dictionary.

Thus, the most efficient and straightforward method is indeed iterating directly over the dictionary, which is accomplished with "for key in my_dict:
