# Mean-Variance-Standard - Unsupported operand type(s)

Still struggling

def calculate(list):
calculations = {}
try:
a = np.array(list).reshape(3, 3)
except:
raise ValueError('List must contain nine numbers.')
calculations['mean'] = [a.mean(axis=0).tolist(), a.mean(axis=1).tolist(), a.mean()]
calculations['variance'] = [a.var(axis=0).tolist(), a.var(axis=1).tolist(), a.var()]
calculations['standart deviation'] = [a.std(axis=0).tolist(), a.std(axis=1).tolist(), a.std()]
calculations['max'] = [a.max(axis=0).tolist(), a.max(axis=1).tolist(), a.max()]
calculations['min'] = [a.min(axis=0).tolist(), a.min(axis=1).tolist(), a.min()]
calculations['sum'] = [a.sum(axis=0).tolist(), a.sum(axis=1).tolist(), a.sum()]

return calculations

2 same errors occured:
