Question

我有一个Python字典，其中列出了为该值定义的列表。我无法以我需要的格式打印输出。

dict = {1 : [2,3], 2 : [1,4], 3 : [2,4], 4 : [2,3]}

需要的打印格式：

1 - 2, 1 - 3
2 - 1, 2 - 4
3 - 2, 3 - 4
4 - 2, 4 - 3

代码：

dict = {1 : [2,3], 2 : [1,4], 3 : [2,4], 4 : [2,3]}
for key, value in sorted(dict.items()):
    for links in value:
        print ("{} - {},".format(key, links)),

输出：

1 - 2, 1 - 3, 2 - 1, 2 - 4, 3 - 2, 3 - 4, 4 - 2, 4 - 3,

或者：

for key, value in sorted(dict.items()):
    for links in value:
        print ("{} - {},".format(key, links))

1 - 2,
1 - 3,
2 - 1,
2 - 4,
3 - 2,
3 - 4,
4 - 2,
4 - 3,

Answer 1

for key, value in sorted(dict.items()):
    print ', '.join(("{} - {}".format(key, links)) for links in value)

Answer 2

dictionary = {1: [2, 3], 2: [1, 4], 3: [2, 4], 4: [2, 3]}

for key, links in sorted(dictionary.items()):
    print("{key} - {}, {key} - {}".format(*links, key=key))

Answer 3

>>> for key, value in sorted(d.items()):
        print('{} - {}, {} - {}'.format(key, value[0], key, value[1]))


1 - 2, 1 - 3
2 - 1, 2 - 4
3 - 2, 3 - 4
4 - 2, 4 - 3

Python打印字典键，值为列表时的值。在单独的行上打印每个键，值
