I have this array : 

```
list = [4,4,4,4,5,5,5,5,9,9,9,9]

And i want to use this array like that:

for i in list:
    print(i)

```

Of course here i have this result:

```
4
4
4
4
5
5
5
5.....

```

But i want to print this in my loop without change my list like list[::4], just in my loop:

```
4
5
9

```

In my list I have 4 times the same number and I just want to print 1 number every 4 occurances.

Please help me !
