CvScalar to Python

I am trying to replace the following C++ and OpenCv code to python. I tried looking around and thought of the following python code but not sure it's the correct way to express CvScalar. Appreciate the help!

For C++ (opencv):

CvScalar lambdaSqrt;
lambdaSqrt.val[0]=10;

For python:

lambdaSqrt = []
lambdaSqrt[0] = 10
