# Strings with given frequency

Is there a sage function that gives me all vectors/strings/lists/tuples of integers with given "absolute frequency"? i.e.

dwim([2, 1]) == ["001", "010", "100"]

What you want is probably `Permutations`

```
sage: P = Permutations([0]*2+[1])
sage: P.list()
[[0, 0, 1], [0, 1, 0], [1, 0, 0]]
```
