* fix: Syntax Error lgtm display in matrix/matrix_operation.py.
* Testing for None should use the 'is' operator.
* fix: Too many arguments for string format.
* fix: supress lgtm alert as false positive.
* style: Unnecessary 'pass' statement.
* Revert "fix: Syntax Error lgtm display in matrix/matrix_operation.py."
