How to fix invalid syntax else error?

[Karen Rosen]

This is the first time I am attempting this - someone was kind enough to help me with my previous error and told me to add print statements before the error which I did the error is now invalid syntax else: on line 130

class BadLine(Exception):
    pass

def isblank(item):
    return len(item) == 0 or item.isspace()

def triad(key,data):
    try:
        assert key in fields
    except:
        print "key %s not found" %key
        raise ValueError,key
print data
print fields2
print key

item = data[fields2[key]]
if key in noblanks:
        item = item.replace(" ","")
if key.startswith("_"):
        key = key.replace("_","")    # hack for double column names
if isblank(item):
        if defaults:
            if key in defaults.keys():
                return  "<%s>"%key+defaults[key]+"</%s>"%key
            else:
                return  "<%s>"%key+"(inconnu)</%s>"%key

This if/else block is invalid:

            if key in defaults.keys():
                return  "<%s>"%key+defaults[key]+"</%s>"%key
            else:
                return  "<%s>"%key+"(inconnu)</%s>"%key
            else:
            print line

Can you see it?
