Fix lgtm error display #1024 (#1190)

* 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."

This reverts commit 4c629b4ce1.
