I don't really care about this, but if you really want to improve the readability while sticking to PEP8, add an empty line between each of the self.look_for_content_and_continue(...) calls. Further, Each line could be like this:

self.look_for_content_and_continue(
    "map",
    ['size=5 {', 'hello', 'world', 'this', 'is', 'me'])

Also, add a note like "Improve readability around these changes while at it" in the commit message.

As I said above, I really don't care you make these changes or not.
