I don't see any reference to nydata before its insert() operation,
so I would expect a NameError exception.

nydata.insert(0, 'hej') looks in the module namespace for an "nydata",
and then looks in that object's namespace for an "insert" attribute.
I guess you may want to bind that name to an initially empty list,
nydata = [].
