import traceback

def main():
    func1()

def func1():
    func2()

def func2():
    log_backtrace()

    if not test.verify(False, "message"):
        log_backtrace()

def log_backtrace():
    backtrace_frames = traceback.extract_stack()

    filename, line_number, function, code = backtrace_frames[0]
    msg = "Backtrace: %s:%s: %s()\n" % (filename, line_number, function)
    detail = ""
    for frame in backtrace_frames[:-1]:
        filename, line_number, function, code = frame
        detail += "%s:%s: %s()\n" % (filename, line_number, function)
    test.log(msg, detail)
test.py

Resulting log entries (message in first line, details after that):
