python - 如何在 pdb 中使用 'debug' 命令(python)

Question

我想知道如何在pdb中使用debug命令？

(Pdb) help

Documented commands (type help <topic>):
========================================
EOF    c          d        h         list      q        rv       undisplay
a      cl         debug    help      ll        quit     s        unt
alias  clear      disable  ignore    longlist  r        source   until
args   commands   display  interact  n         restart  step     up

break  cont       enable   jump      p         retval   u        whatis
bt     continue   exit     l         pp        run      unalias  where

Miscellaneous help topics:
==========================
pdb  exec
(Pdb) help debug
debug code
        Enter a recursive debugger that steps through the code
        argument (which is an arbitrary expression or statement to be
        executed in the current environment).
(Pdb) debug print('hello')
ENTERING RECURSIVE DEBUGGER
> <string>(1)<module>()->None
((Pdb)) n
hello
--Return--
> <string>(1)<module>()->None
((Pdb)) n
LEAVING RECURSIVE DEBUGGER
