Check->Indentations checks for Whitespace related problems using the standard Python module tabnanny. Feeding your script to tabnanny (python -mtabnanny script.py) doesn't result in an output meaning, everything is ok. Tabnanny basically checks for identations that use a mixture of tabs and spaces. It doesn't catch syntax errors. That is the job of Check->Syntax.
