Whenever you add an element whose key already exists, it’s value will get changed to the new value. A dictionary is a collection of key:value pairs. In this python program, we are using For Loop to iterate each element in this Dictionary. To access the keys alone of a Python Dictionary, use the iterator returned by dict.keys(). Then as we loop through num_list, which will be the list passed as an argument to the function, using a for loop, we are creating key:value pairs in count_dict. keys() returns an iterable list of dictionary keys. We will learn by using a loop, using items() method and by iterating through all keys. For example, declare a dictionary of random categories and print it out using items(). The key will equal the current number we are on while iterating through num_list , and its corresponding value is equal to the count of that number in num_list . Each time you create and assign new key and value, it gets appended to the end of the dictionary in Python. To loop through a dictionary, we can use Python for loop. We can create loops in Python using for loop and while loop. Python dictionaries have a built-in function called items() which returns an iterable object that will display the dictionaries’ key-value pairs in the form of a tuple. While analyzing data using Python data structures we will eventually come across the need for accessing key and value in a dictionary. In python, dictionary is a collection of an unordered sequence of key-value pair items. Then use Python For Loop to iterate through those keys.
