That's not the output of to_string.
to_string is a method, not an attribute which is apparent by the

comment in your output.
You need to call it with parenthesis like `dframe.to_string()`

As for re-importing, serialize the frame to something sensible first.
There are several options available, csv, json, html... Take your pick.

You can find all those in the dframe.to_$something namespace
(again, those are methods, make sure to call them).

Import it again with pandas.read_$something, choosing the same serialization format
you picked for the output in the first place.

Does this help?
