“ else”子句有什么问题？
for filename in files: try: im = Image.open(os.path.join(dirname,filename)) except IOError, e: print "error opening file :: %s : %s" % (os.path.join(dirname,filename), e) else: print im.size
现在，由于您处于循环中，因此还可以使用“ continue”语句：
for filename in files: try: im = Image.open(os.path.join(dirname,filename)) except IOError, e: print "error opening file :: %s : %s" % (os.path.join(dirname,filename), e) continue print im.size
