I would appreciate it if you can check whether my code is correct and write 5 pytests for different cases for it.

The Pytest format is :

def test_function name_1:

assert function name==blablabla

def multiplyScalarMatrix (matrixl, scalar): Input: matrixl is a list, scalar is an integer. If incorrect input types are given, return None. Otherwise, return the list that represents a matrix that is the product of matrixl and scalar. if type (matrixl) !=list or type (scalar) !=int: return None for i in range (len (matrixl)): for j in range (len (matrixl[i])): matrixl[i][j] *= scalar return matrixl def multiplyScalarMatrix (matrixl, scalar): Input: matrixl is a list, scalar is an integer. If incorrect input types are given, return None. Otherwise, return the list that represents a matrix that is the product of matrixl and scalar. if type (matrixl) !=list or type (scalar) !=int: return None for i in range (len (matrixl)): for j in range (len (matrixl[i])): matrixl[i][j] *= scalar return matrixl
