I think we need to escape the `\`. So basically instead of `\` use `\\` ``` /home/nero/repos/aptly/python-aptly/aptly/publisher/__init__.py:179: SyntaxWarning: invalid escape sequence '\}' nodes_raw = re.findall('[ \t]+"([^"]+)".*label="{(Repo|Snapshot|Published) ([^|]+)[^\}"]+}"', dot_data) /home/nero/repos/aptly/python-aptly/aptly/publisher/__init__.py:591: SyntaxWarning: invalid escape sequence '\ ' parsed = re.match('(.*)\ (.*)\ (.*)\ (.*)', ref) ```
