可变范围并尝试在python中捕获

“ 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
