The Python Debugger Pdb
=======================
To use the debugger in its simplest form:
>>> import pdb
>>> pdb.run('')
The debugger's prompt is '(Pdb) '. 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.

(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.

Without argument, list all breaks.
With a line number argument, set a break at this line in the
current file. With a function name, set a break at the first
executable line of that function. If a second argument is
present, it is a string specifying an expression which must
evaluate to true before the breakpoint is honored.
The line number may be prefixed with a filename and a colon,
to specify a breakpoint in another file (probably one that
hasn't been loaded yet). The file is searched for on
sys.path; the .py suffix may be omitted.

The current line in the current frame is indicated by "->".
If an exception is being debugged, the line where the
exception was originally raised or propagated is indicated by

Create an alias called 'name' that executes 'command'. The
command must *not* be enclosed in quotes. Replaceable
parameters can be indicated by %1, %2, and so on, while %* is
replaced by all the parameters. 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

Execute the (one-line) statement in the context of the current
stack frame. The exclamation point can be omitted unless the
first word of the statement resembles a debugger command. To
assign to a global variable you must always prefix the command
with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']

Debug the Python program given by pyfile. Alternatively,
an executable module or package to debug can be specified using
the -m switch.
Initial commands are read from .pdbrc files in your home directory
and in the current directory, if they exist. Commands supplied with
-c are executed after commands from .pdbrc files.
To let the script run until an exception occurs, use "-c continue".
To let the script run up to a given line X in the debugged file, use
