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)
