# All possible permutations of combinations of dictionaries from 2 lists

Suppose I have 2 lists in python:

``````keys = [1, 2, 3, 4, 5, 6]

values = [7, 8, 9]
```

(adsbygoogle = window.adsbygoogle || []).push({});

```

I want to get all permutations from these 2 lists

something like:

``````d = [{1:7, 2:8, 3:9}, {1:8, 2:9, 3:7}, ....... ]
```

(adsbygoogle = window.adsbygoogle || []).push({});

```

How could I achieve this?

Do you mean something like this?

``````>>> import itertools
>>> keys = [1, 2, 3, 4, 5, 6]
>>> values = [7, 8, 9]
>>> d = [dict(zip(kperm, values)) for kperm in itertools.permutations(keys, len(values))]
>>> len(d)
120
>>> d[:10]
[{1: 7, 2: 8, 3: 9}, {1: 7, 2: 8, 4: 9}, {1: 7, 2: 8, 5: 9}, {1: 7, 2: 8, 6: 9}, {1: 7, 2: 9, 3: 8}, {1: 7, 3: 8, 4: 9}, {1: 7, 3: 8, 5: 9}, {1: 7, 3: 8, 6: 9}, {1: 7, 2: 9, 4: 8}, {1: 7, 3: 9, 4: 8}]
```

(adsbygoogle = window.adsbygoogle || []).push({});

```
