U+2010 isn't allowed in Python 3 identifiers.

The rules for identifiers are here: 
https://docs.python.org/3/reference/lexical_analysis.html#identifiers 
.   U+2010 is in category Pd 
(http://www.fileformat.info/info/unicode/char/2010), which isn't one of 
the categories allowed in identifiers.  Category Pc 
(http://www.fileformat.info/info/unicode/category/Pc/list.htm) is 
allowed, but it doesn't include anything that would look like a hyphen.
