kindly help and tell what im doing wrong

**Your code so far**

```
import numpy as np
def calculate(list):
if len(list) ! = 9 :
raise ValueError("list must contains nine number")
list = np.array(list).reshape((3, 3))
mean = [list.mean(axis=0).tolist(),list.mean(axis=1).tolist(), np.mean(list).tolist()]
variance = [list.variance(axis=0).tolist(),list.variance(axis=1).tolist(), np.variance(list).tolist()]
std_dev = [list.std(axis=0).tolist(),list.std(axis=1).tolist(), np.std(list).tolist()]
max = [list.max(axis=0).tolist(),list.max(axis=1).tolist(), np.max(list).tolist()]
min = [list.min(axis=0).tolist(),list.min(axis=1).tolist(), np.min(list).tolist()]
sum = [list.sum(axis=0).tolist(),list.sum(axis=1).tolist(), np.sum(list).tolist()]
return{
"mean" : mean,
"variance" : variance,
"standard deviation" : std_dev,
"max" : max,
"min" : min,
"sum" : sum,
}
```
