[FIXED] How do I create a multidimensional lambda function in Python?

Issue

I am using the code shown below but doesn't work...

For example, I want to put

X=[2,2,2] 

then

S(X)=sum([4,4,4]+[1,1,1])=15

S=lamda X:sum(X**2+np.ones(3))
S(2*np.ones(3))

Solution

You should replace lamda with lambda.

X=[2,2,2]
S=lambda X:sum(X**2+np.ones(3))
print S(2*np.ones(3))

Output:

15.0

I edited your question because I thought it was a typo but the change was rejected. I agree that the typo is the only problem so I am submitting this as an answer.
