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,…
The intersection() method checks the intersection of items between two or more sets, that is, items that exist in all sets. In the example below both sets together have the item ‘bmw’. car_brands_set_one = {'bmw', 'mclaren', 'ferrari'} car_brands_set_two = {'honda',…
The hasattr() function checks if an object has a certain attribute. The first argument is the object being checked and the second argument is the attribute. If the attribute exists in the object the method returns True, otherwise it returns…
Use the find() method to check if a string has certain substring. The method returns the index of the first occurrence of the given value. Remember the index count starts at 0. phrase = "This is a regular text" print(phrase.find('This'))…
The round() function rounds a given number with the specified number of decimals. If you don’t specify the number of decimals, the default will be zero decimals. print(round(32.8476)) print(round(32.8476,1)) print(round(32.8476,2)) print(round(32.8476,3)) 33 32.8 32.85 32.848
Use the built-in extend() method from list to add all the items of an iterable to the end of a list. The method doesn’t return any value, it alters the original list. Lists, sets and tuples are examples of iterables.…
The issubset() method checks if a set is a subset 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 subset of another, or False…
