Python中的dict()怎么用？

Question

hi，各位大牛，新手上路，对工厂函数不太理解，dict()怎么用？

Answer 1

dict(one=1, two=2)

dict({'one': 1, 'two': 2})

dict(zip(('one', 'two'), (1, 2)))

dict([['two', 2], ['one', 1]])

Answer 2

help(dict)看帮助....

简单说，就是生成一个{}

Answer 3

内置的文档很详细了

    dict() -> new empty dictionary

    dict(mapping) -> new dictionary initialized from a mapping object's

        (key, value) pairs

    dict(iterable) -> new dictionary initialized as if via:

        d = {}

        for k, v in iterable:

            d[k] = v

    dict(**kwargs) -> new dictionary initialized with the name=value pairs

        in the keyword argument list.  For example:  dict(one=1, two=2)
