Why does the error "TypeError: () takes 1 positional argument but 2 were given" come out?
I am making a matrix calculator, I want to use recursion, but this error pops up:
1. Add matrices
2. Multiply matrix by a constant
3. Multiply matrices
4. Transpose matrix
5. Calculate a determinant
0. Exit
Your choice: 5
Enter size of matrix: 3 3
Enter matrix:
1 2 3
4 5 6
7 8 9

The problem is with this call.
def find_determinant(self):
self.__print_matrice__(super().find_determinant(*self.__create_matrice__()))
