This class takes care of details of the trace facility; a derived class should implement user interaction. The standard debugger class (pdb.Pdb) is an example. The optional skip argument must be an iterable of glob-style module name patterns. The debugger will not step into frames that originate in a module that matches one of these patterns. Whether a frame is considered to originate in a certain module is determined by the __name__ in the frame globals.

This function is installed as the trace function for debugged frames. Its return value is the new trace function, which is usually itself. The default implementation decides how to dispatch a frame, depending on the type of event (passed in as a string) that is about to be executed. The event can be one of the following: line: A new line of code is going to be executed. call: A function is about to be called or another code block is entered. return: A function or other code block is about to return. exception: An exception has occurred. c_call: A C function is about to be called. c_return: A C function has returned. c_exception: A C function has raised an exception. For the Python events, specialized functions (see the dispatch_*() methods) are called. For the C events, no action is taken. The arg parameter depends on the previous event.
