Python之字典对象的几种创建方法

firstDict = {"name": "wang yuan wai ", "age" : 25}

second_dict = dict.fromkeys(("name", "age")) #value使用默认的None,也可以指定value值

thirdDict = dict(name = "yuan wai", age = 30) #利用dict的构造方法 传入字典参数

tuple_list =[("name", "wang yuan wai"), ("age", 30)]

fifthDict = dict(zip("abc",[1,2,3]))

sixthDict = {char : char* 2 for char in "TEMP"}

> a = dict(one=1, two=2, three=3)
> b = {'one': 1, 'two': 2, 'three': 3}
> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
> d = dict([('two', 2), ('one', 1), ('three', 3)])
> e = dict({'three': 3, 'one': 1, 'two': 2})
> a == b == c == d == e
True
