1. 最ｐｙｔｈｏｎ方法，简单的实现　删除多个ｋｅｙｓ　

myDict = {'a': 1, 'b': 2, 'c': 3, 'd': 4}map(myDict.pop, ['a', 'c'])print myDict

###2. dict删除ｋｅｙｓ，原有的ｄｉｃｔ却不变

def without(d, key):    # 复制一个新的ｄｉｃｔ    new_d = d.copy()    new_d.pop(key)    return new_d

###3. 字典推导式法，构造一个新的字典 final_dict = {key: t[key] for key in t if key not in [key1, key2]}

a = {'a': 1, 'c': 3, 'b': 2, 'd': 4}keys = ["b", "c"]print {key: a[key] for key in a if key not in keys}

###4. 递归删除keys,包括子部分包含keys

def dict_del_keys(data, del_keys):    if isinstance(data, dict):        new_dict = {}        for key in data.keys():            if key not in del_keys:                new_dict[key] = dict_del_keys(data[key], del_keys)        return new_dict     else:        return data
