The difference() method checks the difference between two sets. It returns a new set of the items contained in the first set that are not in the second set. In the example below, both sets have ‘bmw’, but ‘mclaren’ and…
The union() method merges as many sets as you want and returns a new set as a result. The items in the new set are unique, meaning no repetitions. In the example below both sets together should equal 6 items,…
The isdisjoint() method checks for items that exist in both sets. If one or more items exist in both sets, the method returns False, otherwise it returns True, which means the Sets are disjoint. car_brands_set_one and car_brands_set_two have ‘bmw’ in…
Use the buit-in index() method from tuple to find the index of an item in a tuple. Remember the index count starts at 0, so the position of ‘mclaren’ is 2. car_brands = ('bmw', 'ferrari', 'mclaren') position = car_brands.index('mclaren') print(position)…
The popitem() method removes the last item inserted in a dictionary. The method returns the removed item as a tuple. In this example, a have a dictionary named people with three items, 'Sarah':32 is the last one. When I use…
The filter() function will filter an iterable based on a given function. Dictionaries, lists, and tuples are examples of iterables. The first argument is the function name, the second argument is the iterable. Let’s filter to have only the numbers…
The map() function applies a function to each item in an iterable. Dictionaries, lists, and tuples are examples of iterables. The first argument is the function name, the second argument is the iterable. Let’s calculate the cubic of each number…
To count the number of occurrences of an item in a Tuple, just use the count() method. car_brands = ('ferrari', 'bmw', 'mclaren', 'bmw', 'bmw', 'ferrari') print(car_brands.count('bmw')) print(car_brands.count('ferrari')) 3 2
The issuperset() method checks if a set is a superset of another set, that is, if all the items of one set exist in the other set. The method returns True if one set is a superset of another, or…
The sum() function allows you to sum all of the items of an iterable in Python. Dictionaries, lists, and tuples are examples of iterables. This example sums the numbers 4, 8, 16, 32, 64 of a list. my_list = [4,…
