SBTarget supports module and breakpoint iterations. For example,

    for m in target.module_iter():
        print m

produces:

(x86_64) /Volumes/data/lldb/svn/trunk/test/python_api/lldbutil/iter/a.out
(x86_64) /usr/lib/dyld
(x86_64) /usr/lib/libstdc++.6.dylib

(x86_64) /usr/lib/system/libmathCommon.A.dylib
(x86_64) /usr/lib/libSystem.B.dylib(__commpage)

and,

    for b in target.breakpoint_iter():
        print b

produces:

SBBreakpoint: id = 1, file ='main.cpp', line = 66, locations = 1
SBBreakpoint: id = 2, file ='main.cpp', line = 85, locations = 1"

    launches a new process by passing nothing for both the args and the envs
    and redirect the standard output of the inferior to the /tmp/stdout.txt
    file. It does not specify a working directory so that the debug server
    will use its idea of what the current working directory is for the
    inferior. Also, we ask the debugger not to stop the inferior at the
    entry point. If no breakpoint is specified for the inferior, it should
    run to completion if no user interaction is required.
