Can python quickly display results like bash?

[robert song]

thank you, it works with -m trace.

As to sh -x, it is used to expand the variables of command, and display it
before executing.

$ info bash
    * The `-x' (`xtrace') option displays commands other than simple
     commands when performing an execution trace (*note The Set
     Builtin::).
