Solve the following python programming problem given the following code:
@ app.route ('/<path:path>') 
def proxy(path) : 
    if (path == 'favicon.ico') : 
        abort (404) 
url = path 
    if (not path.count ('://')) : 
        url = ('http://' + url) 
query = urlparse (request.url).query 
    if query : 
        url += ('?%s' % query) 
logging.info (('Downloading %s' % url)) 
    t0 = time.time () 
    html = download (url) 
    t1 = time.time () 
    print (('%.4f seconds to download' % (t1 - t0))) 
    p = Processor (debug = False, optimize_lookup = True) 
    t0 = time.time () 
    p.process_html (html, url) 
    t1 = time.time () 
    p.process () 
    t2 = time.time () 
    print (('%.4f seconds to parse and process' % (t2 - t1))) 
    collect_stats = request.args.get ('MINCSS_STATS', False) 
    stats = [] 
    css_url_regex = re.compile ('url\\(([^\\)]+)\\)') 
    def css_url_replacer(match, href = None) : 
        filename = match.groups () [0] 
        bail = match.group () 
        if ((filename.startswith ('"') and filename.endswith ('"')) or (filename.startswith ("'") and filename.endswith ("'"))) : 
            filename = filename [1 : (- 1)] 
if (('data:image' in filename) or ('://' in filename)) : 
            return bail 
if (filename == '.') : 
            return bail 
new_filename = urljoin (url, filename) 
        return ('url("%s")' % new_filename) 
for (i, each) in enumerate (p.inlines) : 
        new_inline = each.after 
        new_inline = css_url_regex.sub (functools.partial (css_url_replacer, href = url), new_inline) 
        stats.append ((('inline %s' % (i + 1)), each.before, each.after)) 
        html = html.replace (collect_stats.before, new_inline) 
parser = etree.HTMLParser () 
    stripped = html.strip () 
    tree = etree.fromstring (stripped, parser).getroottree () 
    page = tree.getroot () 
    was_doctype = tree.docinfo.doctype 
    links = dict (((x.href, x) for x in p.links)) 
    for link in CSSSelector ('link') (page) : 
        if ((link.attrib.get ('rel', '') == 'stylesheet') or link.attrib ['href'].lower ().split ('?')...

    
    

    Fix the buggy line: html = html.replace (collect_stats.before, new_inline)
assistant
#Here is Python program to fix the buggy line: html = html.

html = html.replace (each.before, new_inline)
