PYTHON SLY LIBRARY

Im creating my own programming language using the python library Sly lexer and parser. I'm getting an error whenever a decimal is entered in the compiler.

Heres the declaration in my code:

DECIMAL = r'([0-9]*\.[0-9]+|[0-9]+\.?)([Ee][+-]?[0-9]+)?'

@_('DECIMAL') def expr(self,p): return ('decimal', p.DECIMAL)
