I need a code solution in python 3 for matrix-vector multiplication using a similar code in the second picture. Please show step by step will rate thank you!

def matVec(matrix,vector): You will need to follow the following specifications: All variable names must be consistent.i.e. You should not do something like name a matrix variable 'A' but then name a vector variable vector. You may choose any naming scheme you would like, so long as you are consistent throughout your code. Your code should contain comments explaining what the different parts of your code is doing and all functions in your script should contain a docstring which explains what your function does and how it does it. Once you have written your function you need to test it using various inputs. I recommend that you make this part of the same script in which you write your function, but this is not required. You should test your function by passing the following inputs A matrix and a vector (the expected inputs) A vector and a matrix l.e. pass a matrix as the vector argument and a vector as the matrix argument) A string and an integer
