Python打印字典键，值为列表时的值。打印每个键，在单独的行上的值

Question

我有一个Python字典和一个为该值定义的列表。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]} 

所需打印格式：

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
