- Exercise: Least Dictionary Value Description In this exercise you will find the value in a dictionary with the least value. Least means that the value is less than or equal to all other values in the dictionary. Remember that the 2 Assistant Object inspectorarrow_forwardSuppose a dictionary named inventory exists. What does the following statement do?del inventory[654]arrow_forwardData structures concatenate_dict(dict_list:list)->dict This function will be given a single parameter known as the Dictionary List. Your job is to combine all the dictionaries found in the dictionary list into a single dictionary and return it. There are two rules for adding values to the dictionary: 1. You must add key-value pairs to the dictionary in the same order they are found in the Dictionary List. 2. If the key already exists, it cannot be overwritten. In other words, if two or more dictionaries have the same key, the key to be added cannot be overwritten by the subsequent dictionaries. Example: Dictionary List: [{'Z': 6, 'k': 10, 'w': 3, 'I': 8, 'Y': 5}, {'Y': 1, 'Z': 4}, {'X': 2, 'L': 5}] Expected: {'Z': 6, 'k': 10, 'w': 3, 'I': 8, 'Y': 5, 'X': 2, 'L': 5} Dictionary List: [{'z': 0}, {'z': 7}] Expected: {'z': 0} Dictionary List: [{'b': 7}, {'b': 10, 'A': 8, 'Z': 2, 'V': 1}] Expected: {'b': 7, 'A': 8, 'Z': 2, 'V': 1}arrow_forward
