You can also invoke "pdb" from the command line to debug other
scripts. For example:
- python -m pdb myscript.py
+ python -m pdb [-c command] (-m module | pyfile) [args ...]
When invoked as a module, pdb will automatically enter post-mortem
debugging if the program being debugged exits abnormally. After post-
as breakpoints) and in most cases is more useful than quitting the
debugger upon program’s exit.
-Changed in version 3.2: Added the "-c" option to execute commands as
-if given in a ".pdbrc" file; see Debugger Commands.
+-c, --command <command>
-Changed in version 3.7: Added the "-m" option to execute modules
-similar to the way "python -m" does. As with a script, the debugger
-will pause execution just before the first line of the module.

trailing zeros are not removed from the result.
-The "','" option signals the use of a comma for a thousands separator
