1.标准的写法
dic = {"K1":"V1","K2":"V2"}dic2 = dict(K1="V1",K2="V2")print(type(dic))print(type(dic2))
2.get和正常的去键值一样，只是当键值不存在时则默认返回None&或者返回指定值
zidian = {"K1":"v1","K2":"v2"}print(zidian["K1"])print(zidian["K2"])print(zidian.get("K3","qiuwenbin"))
结果：
v1v2qiuwenbin
3.pop 拿走字典中的键值------由于字典是无序的，所以pop后的参数是必须的。
zidian = {"K1":"v1","K2":"v2"} print(zidian.pop("K1")) print(zidian)
