Variable scope and Try Catch in python

What’s wrong with the “else” clause ?

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

Now since you’re in a loop, you can also use a “continue” statement:

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
