PHPのXdebugみたいな感じ。
PyPIに登録した。
今のところ、1.2.2が最新。

Usage

Usage: pyxdebug.py [-o output_file_path] [-i collect_import] [-p collect_params] [-r collect_return] [-a collect_assignments] script_path [args ...]

Options:
  -h, --help            show this help message and exit
  -o, --outfile         Save stats to <outfile>
  -i, --collect_imports
                        This setting, defaulting to 1, controls whether
                        PyXdebug should write the filename used in import or
                        reload to the trace files.
  -p, --collect_params  This setting, defaulting to 0, controls whether
                        PyXdebug should collect the parameters passed to
                        functions when a function call is recorded in either
                        the function trace or the stack trace.
  -r, --collect_return  This setting, defaulting to 0, controls whether
                        PyXdebug should write the return value of function
                        calls to the trace files.
  -a, --collect_assignments
                        This setting, defaulting to 0, controls whether
                        PyXdebug should add variable assignments to function
                        traces.
