enumerate()
In case if you need extract both index and value from the iterable object, use enumerate():
123nums = [2, 3, 5, 7, 11, 13, 17, 19, 23, 29] for idx, val in enumerate(nums): print(f'{idx}th prime number is: {val}')

Given a list of movies in the cinema. Starting with index 0, each element in the array is the name of the movie in production on the i-th day. Transform this data by creating a dictionary schedule that for each movie as key stores the list of days when this movie screenings are. For example:
movies = ['Shrek', 'Snow White', 'Cars', 'Cars', 'Shrek', 'Shrek 2'] =>
schedule = {
'Cars': [2, 3],
'Shrek': [0, 4],
'Shrek 2': [5],
'Snow White': [1]
}
Remember about case if movie is not in dict already.
