Python Question

`listA = ["A","B","C","D"]`

From this, I want the following output only:

`["A","B","C"]`

["B","C","D"]

["C","D","A"]

["D","A","B"]

I have looked at various questions on permutations here, but I am not able to do achieve this so far. Any help will be appreciated.

another way to do this - brute force,

```
def permutation(L):
for i in range(len(L)):
x = L[i:i+3]
length = len(x)
if length != 3:
x = x + L[:3-length]
print(x)
L = ["A","B","C","D"]
permutation(L)
```
