`array1=[ 0 5 6 6 6 0 6 0 6 8 0 19 24 7 0 4 9 14 12 0 22 17 1 0 19 6 17 4 7 0 17 24 0 6 9 22]`

```
i=0
while i<23
      m= array1.count(i)
      i=i+1

```

`AttributeError: 'numpy.ndarray' object has no attribute 'count'`

Why does attribute error appear when i use .count()? do I need to import something?
