What is/are the Python equivalent(s) to the Java Collections Framework?

问题

The Java Collections Framework is like the C++ Standard Template Library: "a unified architecture for representing and manipulating collections (objects that group multiple elements into a single unit)."

回答1:

Other than the built-ins you might what to check out collections.

>>> import collections
>>> dir(collections)
['Callable', 'Container', 'Hashable', 'ItemsView', 'Iterable', 'Iterator', 'KeysView', 'Mapping', 'MappingView', 'MutableMapping', 'MutableSequence', 'MutableSet', 'Sequence', 'Set', 'Sized', 'ValuesView', '__all__', '__builtins__', '__doc__', '__file__', '__name__', '__package__', '_abcoll', '_iskeyword', '_itemgetter', '_sys', 'defaultdict', 'deque', 'namedtuple']

As it turns out, the equivalent to the Java Collections Framework in Python is... Python. All of the core collections featured in the Java Collections Framework are already present in core Python.

Give it a try! Sequences provide lists, queues, stacks, etc. Dictionaries are your hash-tables and maps. Sets are present, etc.

One might consider Python a "higher" language than Java, because it natively provides all of these higher order abstract data types intrinsically. (It also supports Object Oriented, procedural, and functional programming methodologies.)
