I'd suggest the following. Works for me, anyway.  :-)

        if yerr is not None: assert (len(yerr)==nbars or (len(yerr)==2
and len(yerr[0])==len(yerr[1])==nbars)), 'bar() argument \'yerr\' must
be len(%s) (or a pair of such) or scalar' % lenarg

        if xerr is not None: assert (len(xerr)==nbars or (len(xerr)==2
and len(xerr[0])==len(xerr[1])==nbars)), 'bar() argument \'xerr\' must
be len(%s) (or a pair of such) or scalar' % lenarg
