Consistent use of indentation is important in a langauge like Python, where white-space is significant. The tabnanny module provides a scanner to report on "ambiguous" use of indentation. The simplest way to use tabnanny is to run it from the command line, passing the names of files to check. If you pass directory names, the directories are scanned recursively to find .py files to check.

cgitb was originally designed for showing errors and debugging information in web applications. It was later updated to include plain-text output as well, but unfortunately wasn't renamed. This has lead to obscurity and the module is not used as often as it should be. Nonetheless, cgitb is a valuable debugging tool in the standard library.

There are two ways to inject code to watch your Python program run: tracing and profiling. They are similar, but intended for different purposes and so have different constraints. The easiest, but least efficient, way to monitor your program is through a trace hook, which can be used for writing a debugger, code coverage monitoring, or many other purposes.
