When a relative import statement contains more than one period and no module name, SyntaxError is raised. Example: from . import spam # this works from ..spam import eggs # this works from .. import eggs # this raises SyntaxError The problem is in the following line in Grammar/Grammar: import_from: ('from' ('.'* dotted_name \| '.') According to Guido's mail: http://mail.python.org/pipermail/python-dev/2003-December/041065.html that line should be: import_from: ('from' ('.'* dotted_name	'.'+)

(My first few patches actually did this right, but Guido suggested an alternative (simpler) spelling of the Grammar rule, and we both forgot the '+' :) Fixed and testcase added in 46209 and 46210. Thanks!
