如何在python打印中打印列表?

我试图构建一个可变数量的参数记录器,如下所示。我想这样称呼它:

log( 1, "Index: ", request_index, ", ", section )

def log(level, *msg) :

    global print_debug_lastTime
    currentTime = datetime.datetime.now().microsecond

    # You can access global variables without the global keyword.
    if g_debug_level & level != 0:

        print( "[DEBUG] " \
                + "%02d" % datetime.datetime.now().hour + ":" \
                + "%02d" % datetime.datetime.now().minute + ":" \
                + "%02d" % datetime.datetime.now().second + ":" \
                + str( currentTime ) \
                + "%7d " % ( currentTime - print_debug_lastTime ) \
                + for m in msg )

>>> print( str( x ) for x in (0,1,2,3) )
<generator object <genexpr> at 0x6ffffe5e550>

我想打印出来 0123
