I wrote the below code

    def replace_static_url(original, prefix, quote, rest):
        '\n                                Replace    a    single    matched    url.\n                                '
        if rest.endswith('?raw'):
            return original
        if (settings.DEBUG and finders.find(rest, True)):
            return original
        elif ((not static_asset_path) and course_id):
            exists_in_staticfiles_storage = False
            try:
                exists_in_staticfiles_storage = staticfiles_storage.exists(rest)
            except Exception as err:
                log.warning("staticfiles_storage    couldn't    find    path    {0}:    {1}".format(rest, str(err)))
            if exists_in_staticfiles_storage:
                url = staticfiles_storage.url(rest)
            else:
                base_url = AssetBaseUrlConfig.get_base_url()
                excluded_exts = AssetExcludedExtensionsConfig.get_excluded_extensions()
                url = StaticContent.get_canonicalized_asset_path(course_id, rest, base_url, excluded_exts)
                if (AssetLocator.CANONICAL_NAMESPACE in url):
                    url = url.replace('block@', 'block/', 1)
        else:
            course_path = '/'.join(((static_asset_path or data_directory), rest))
            try:
                if staticfiles_storage.exists(rest):
                    url = staticfiles_storage.url(rest)
                else:
                    url = staticfiles_storage.url(course_path)
            except Exception as err:
                log.warning("staticfiles_storage    couldn't    find    path    {0}:    {1}".format(rest, str(err)))
                url = ''.join([prefix, course_path])
        return ''.join([quote, url, quote])
    return process_static_urls(text, replace_static_url, data_dir=(static_asset_path or data_directory))

What's a good function header?
