Hi there! My english is not very good, but I’ll try to explain my self the best possible. I’m having problems with the ‘Exception’ of the project, when the list has just a few numbers (<9). I’d already try with a lot of alternatives and modifications, but I’ve not see which is(are) the detail(s) that are making mistakes in it.

Please help me! Greetings from Chile!

```
import numpy as np
def calculate(list):
try:
if len(list)==9:
a=np.array(list)
b=a.reshape(3,3)
m1=np.mean(b,axis=0).tolist()
m2=np.mean(b,axis=1).tolist()
m3=np.mean(b).tolist()
mean=[m1,m2,m3]
v1=np.var(b,axis=0).tolist()
v2=np.var(b,axis=1).tolist()
v3=np.var(b).tolist()
variance=[v1,v2,v3]
s1=np.std(b,axis=0).tolist()
s2=np.std(b,axis=1).tolist()
s3=np.std(b).tolist()
std=[s1,s2,s3]
ma1=np.max(b,axis=0).tolist()
ma2=np.max(b,axis=1).tolist()
ma3=np.max(b).tolist()
ma=[ma1,ma2,ma3]
mi1=np.min(b,axis=0).tolist()
mi2=np.min(b,axis=1).tolist()
mi3=np.min(b).tolist()
mi=[mi1,mi2,mi3]
su1=np.sum(b,axis=0).tolist()
su2=np.sum(b,axis=1).tolist()
su3=np.sum(b).tolist()
su=[su1,su2,su3]
calculations={'mean':mean, 'variance':variance, 'standard deviation':std, 'max':ma, 'min':mi, 'sum':su}
except ValueError:
print('List must contain nine numbers.')
return calculations
```
