Python Print dictionary key, value when value is a list. Print each key, value on seperate line

Question

I have a Python dictionary with a list defined for the value. I am having trouble printing the output in the format I need.

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

Needed print format:

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

Code:

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)),

Output:

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

Or:

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,

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

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))

>>> 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
>>>

`d.items()` should be `sorted(...)` – SparkAndShine Nov 09 '16 at 22:40
