This will stop in the first function call in . Alternatively, if a statement terminated with an unhandled exception, you can use pdb's post-mortem facility to inspect the contents of the traceback: >>> >>> import pdb >>> pdb.pm() The commands recognized by the debugger are listed in the next section. Most can be abbreviated as indicated; e.g., h(elp) means that 'help' can be typed as 'h' or 'help' (but not as 'he' or 'hel', nor as 'H' or 'Help' or 'HELP'). Optional arguments are enclosed in square brackets. Alternatives in the command syntax are separated by a vertical bar (|). A blank line repeats the previous command literally, except for 'list', where it lists the next 11 lines. Commands that the debugger doesn't recognize are assumed to be Python statements and are executed in the context of the program being debugged. Python statements can also be prefixed with an exclamation point ('!'). This is a powerful way to inspect the program being debugged; it is even possible to change variables or call functions. When an exception occurs in such a statement, the exception name is printed but the debugger's state is not changed. The debugger supports aliases, which can save typing. And aliases can have parameters (see the alias help entry) which allows one a certain level of adaptability to the context under examination. Multiple commands may be entered on a single line, separated by the pair ';;'. No intelligence is applied to separating the commands; the input is split at the first ';;', even if it is in the middle of a quoted string. If a file ".pdbrc" exists in your home directory or in the current directory, it is read in and executed as if it had been typed at the debugger prompt. This is particularly useful for aliases. If both files exist, the one in the home directory is read first and aliases defined there can be overridden by the local file. This behavior can be disabled by passing the "readrc=False" argument to the Pdb constructor. Aside from aliases, the debugger is not directly programmable; but it is implemented as a class from which you can derive your own debugger class, which you can make as fancy as you like.

(com) end (Pdb) Specify a list of commands for breakpoint number bpnumber. The commands themselves are entered on the following lines. Type a line containing just 'end' to terminate the commands. The commands are executed when the breakpoint is hit. To remove all commands from a breakpoint, type commands and follow it immediately with end; that is, give no commands. With no bpnumber argument, commands refers to the last breakpoint set. You can use breakpoint commands to start your program up again. Simply use the continue command, or step, or any other command that resumes execution. Specifying any command resuming execution (currently continue, step, next, return, jump, quit and their abbreviations) terminates the command list (as if that command was immediately followed by end). This is because any time you resume execution (even with a simple next or step), you may encounter another breakpoint -- which could have its own command list, leading to ambiguities about which list to execute. If you use the 'silent' command in the command list, the usual message about stopping at a breakpoint is not printed. This may be desirable for breakpoints that are to print a specific message and then continue. If none of the other commands print anything, you will see no sign that the breakpoint was reached. rz.Usage: commands [bnum] ... endNTFz(com) rr“z1command definition aborted, old commands restored)Úlenr6rÌrÍÚintr•rPrLrMrNr=rOr…rT)r1r­ZbnumZold_command_defsZ prompt_backrrrÚ do_commandssB%   þ    zPdb.do_commandsrc CsB|s8|jr4| d¡tjjD]}|r| | ¡¡qdSd}d}d}| d¡}|dkrz||dd… ¡}|d|… ¡}|  d¡}d} |dkr|d|… ¡}|  |¡} | sÂ|  d|¡dS| }||dd… ¡}z t |ƒ}Wn&t k r |  d|¡YdSXnÀz t |ƒ}Wn²t k rÎzt||jj|jƒ} Wn|} YnXz.t| d ƒrj| j} | j} | j} | j}| j}WnD| |¡\} }}| s¸|  d |¡YYdS| } t |ƒ}YnXYnX|sÞ| ¡}| ||¡}|r>| ||||| ¡}|r|  |¡n*| ||¡d }| d |j|j|jf¡dS) a²b(reak) [ ([filename:]lineno | function) [, condition] ] Without argument, list all breaks.

If no command is given, the current alias for name is shown. If no name is given, all aliases are listed. Aliases may be nested and can contain anything that can be legally typed at the pdb prompt. Note! You *can* override internal pdb commands with aliases! Those internal commands are then hidden until the alias is removed. Aliasing is recursively applied to the first word of the command line; all other words in the line are left alone. As an example, here are two useful aliases (especially when placed in the .pdbrc file): # Print instance variables (usage "pi classInst") alias pi for k in %1.__dict__.keys(): print("%1.",k,"=",%1.__dict__[k]) # Print instance variables in self alias ps pi self rz%s = %sNrrš)rœrÚÚsortedr>r×rUrŸ)r1r­r¥r×r›rrrÚdo_aliasjs "z Pdb.do_aliascCs6| ¡}t|ƒdkrdS|d|jkr2|j|d=dS)z9unalias name Delete the specified alias. rN)rœrÚr>)r1r­r¥rrrÚ do_unaliass  zPdb.do_unaliascs‡fdd„|jDƒS)Ncsg|]}| ˆ¡r|‘qSrrÑ)rÈÚarÊrrrË—s z(Pdb.complete_unalias..)r>rÎrrÊrÚcomplete_unalias–szPdb.complete_unaliasrrrrr#rcCs4z|jD]}| |¡qWntk r.YnXdSr/)r[rwrT)r1Ú frame_linenorrrr¥s  zPdb.print_stack_tracecCs6|\}}||jkrd}nd}| || ||¡¡dS)Nz> z )r]rUZformat_stack_entry)r1rSZ prompt_prefixrWrrƒrrrrw¬s  ÿzPdb.print_stack_entrycCs¨|stj ||¡Sz@zt|d|ƒ}|ƒWWStk rNt|d|ƒ}YnXWn"tk rt| d|¡Yn0Xtjjdkr”| d|¡dS|  |j   ¡¡dS)zýh(elp) Without argument, print the list of available commands.
