Python, how to print dictionary key and its values in each line?

Question

Please see the below image for reference:

Answer 1

Probably something like this:

d = {1:[2,3], 2:[4,5]}

for key in d:
    for i in d[key]:
        print("{0}:{1}".format(key, i))


1:2
1:3
2:4
2:5

Answer 2

>>> for key in d:
...     for item in d[key]:
...         print key, ':', item
1 : 2
1 : 3
2 : 4
2 : 5

Answer 3

use key and value of your dictionary

d={1:[2,3],2:[4,5]}
for k, v in d.items():
    for item in v:
        print(k,' : ',item)

Answer 4

You could do it with a single for loop unpacking a value list each iteration.

d = {1: [2, 3], 2: [4, 5]}

for k in d:
    x, y = d[k]
    print("{} : {}\n{} : {}".format(k, x, k, y))

1 : 2
1 : 3
2 : 4
2 : 5

Because the value lists have just a couple numbers, it can also be done, like so:

for k, v in d.items():
    print("{} : {}\n{} : {}".format(k, v[0], k, v[1]))
