Question

findloc is another subroutine i created,when parse is called sometimes it returns None and sometimes a value, when trying to rstrip I am getting the following error?how to use rstrip only when the object is non “nonetype” or please suggest any other method.

    build_loc=parse(findloc(targetmeta_cid).strip())
    Target_list.append(build_loc.rstrip('\r\n'))

Error

 Target_list.append(build_loc.rstrip('\r\n'))AttributeError: 'NoneType' object has no attribute 'rstrip'

Answer 1

You can this

if build_loc is not None:
    Target_list.append(build_loc.rstrip('\r\n'))

in order to make it work. Hope this helps 🙂
