Tried creating a list of the arguments, however I am creating too many
positional arguments.
matrix1 = [[1, -2], [-3, 4],]
matrix2 = [[2, -1], [0, -1]]
matrix3 = [[2, -1], [0, -1]]
matrix = []
def add_many(a = list(*matrix)):
for num in a:
for i in range(len(matrix[num])):
for j in range(len(matrix[num])):
print(matrix[num][i][j] + matrix[num][i][j])
add_many(matrix1,matrix2)
