Python programming skills - containers, iterators, generators

container Containers can be intuitively imagined as units with multiple elements together, and the difference between different containers lies in the implementation method of internal data structure. Lists (list: [0, 1, 2]), tuples (tuple: (0, 1, 2)), dictionaries (dict: {0:0, 1:1, 2:2}), and collections (set: set([0, 1, 2]) are containers. ...
