我有一个字典:
{'Key_1': ['Value_1'], 'Key_2': ['Value_1', 'Value_2'], 'Key_3': ['Value_2'], 'Key_4': ['Value_3']}
我想获得具有相同值的键,例如,输出如下:
Key_1 and Key_2 have same Value_1
Key_2 and Key_3 have same Value_2
我试图这样做以获得共同的价值观:
list_1 = []
output = []
for value in dictionary.values():
for x in value:
if x in list_1:
if not x in output:
output.append(x)
else:
list_1.append(x)
通过此操作,我可以获得公用值,但没有相应的键。
提前谢谢!
答案 0 :(得分:3)
d = {'Key_1': ['Value_1'], 'Key_2': ['Value_1', 'Value_2'], 'Key_3': ['Value_2'], 'Key_4': ['Value_3']}
out = {}
for k, v in d.items():
for vv in v:
out.setdefault(vv, []).append(k)
for k, v in out.items():
if len(v) > 1:
print('{} have same {}'.format(' and '.join(v), k))
打印:
Key_1 and Key_2 have same Value_1
Key_2 and Key_3 have same Value_2
