list1 = [4356, 'abc']
list2 = {4356: ('5986', '5987'), 6598: ('6593', '2659')}
如何比较基于第一个元素(在这种情况下为'4356'元素)的两个列表,并在添加了'True'单词的字典中将list2中的匹配值获取到字典中?
我需要输出像这样:
output = {'5986':'True', '5987':'True'}
答案 0 :(得分:1)
list1 = [4356, 'abc']
list2 = {4356: ('5986', '5987'), 6598: ('6593', '2659')}
output = {x: True for x in list2[list1[0]]}
print(output) # {'5986': True, '5987': True}
或者,使用您评论中的list2
:
list1 = [4356, 'abc']
list2 = [(4356, '5986'), (4356, '5987'), (6598, '6593'), (6598, '2659')]
output = {val: True for key, val in list2 if key == list1[0]}
print(output) # {'5986': True, '5987': True}
