![]() Using the enumerate() function in this way can be especially useful when you need to keep track of the index of each item in a dictionary. We also use the index variable to keep track of the index of each item as we iterate through the dictionary. Inside the for loop, we use tuple unpacking to assign the key and value of each item in the dictionary to variables. In this example, we use the enumerate() function in combination with the items() method to iterate through the items in the dictionary. However, it can also be used to iterate through the items in a dictionary. The enumerate() function in Python is a built-in function that allows you to iterate through a sequence (such as a list or tuple) and also keep track of the index of each item in the sequence. The order in which the keys are accessible is not guaranteed, therefore this approach might not always be the best one. In conclusion, iterating through a dictionary's keys and values directly using a for loop is a practical and effective method. Use one of the other techniques we've covered, like the items() function, if you need to iterate through a dictionary in a specified order. To put it another way, the keys might not always be used in the same order that they were first added to the dictionary. The order in which the keys are accessible is not ensured while iterating through a dictionary in this manner, it should be noted. ![]() Since you can accomplish both in a single loop, it can be especially helpful when you need to access the dictionary's keys and values. You might want to think about utilising one of the other techniques we covered, like the items() method, if you need to iterate through a dictionary in a specified order. The keys may not be used in the same order that they were first added to the dictionary. It is convenient and effective to iterate through a dictionary's keys and values by using a for loop directly on the dictionary. We employ the square bracket syntax, as in my dict, to get the value for each key. We cycle through the dictionary's keys inside the loop. In this instance, we directly utilise a for loop on the dictionary. The keys in the dictionary can be iterated through by using this view object in a for loop. ![]() ![]() Python's keys() function returns a view object containing a dictionary's keys. It returns a dynamic view object that reflects changes made to the dictionary during the iteration and enables you to access both the dictionary's keys and values in a single loop. Overall, iterating through a dictionary in Python can be done relatively quickly and easily by using the items() method. Instead, the items() method returns a view object that contains both the dictionary's keys and values. This is so that there is no need to use the keys() and values() methods separately and produce two different view objects. The items() method also has the benefit of being more effective than the keys() and values() methods alone. The view object that the items() method returns therefore reflects this modification and displays the new value. In this illustration, we alter the "age" key's value throughout the iteration.
