您可以如下使用简单的递归函数。
def flatten(d): res = [] # Result list if isinstance(d, dict): for key, val in d.items(): res.extend(flatten(val)) elif isinstance(d, list): res = d else: raise TypeError("Undefined type for flatten: %s"%type(d)) return resdict1 = { 'Bob': { 'shepherd': [4, 6, 3], 'collie': [23, 3, 45], 'poodle': [2, 0, 6], }, 'Sarah': { 'shepherd': [1, 2, 3], 'collie': [3, 31, 4], 'poodle': [21, 5, 6], }, 'Ann': { 'shepherd': [4, 6, 3], 'collie': [23, 3, 45], 'poodle': [2, 10, 8], }}print( flatten(dict1) )
