code error

I think
@staticmethod
def __getrelationinfo(lnode, rnode):
""" Get relation information
:type lnode,rnode: SpanNode instance
:param lnode,rnode: Left/Right children nodes
"""
if (lnode.prop == 'Nucleus') and (rnode.prop == 'Nucleus'):
relation = lnode.relation
elif (lnode.prop == 'Nucleus') and (rnode.prop == 'Satellite'):
relation = lnode.relation
elif (lnode.prop == 'Satellite') and (rnode.prop == 'Nucleus'):
relation = rnode.relation
else:
print('lnode.prop = {}, lnode.edu_span = {}'.format(lnode.prop, lnode.edu_span))
print('rnode.prop = {}, lnode.edu_span = {}'.format(rnode.prop, rnode.edu_span))
raise ValueError("Error when find relation for new node")
return relation

should be

@staticmethod
def __getrelationinfo(lnode, rnode):
""" Get relation information
:type lnode,rnode: SpanNode instance
:param lnode,rnode: Left/Right children nodes
"""
if (lnode.prop == 'Nucleus') and (rnode.prop == 'Nucleus'):
relation = lnode.relation
elif (lnode.prop == 'Nucleus') and (rnode.prop == 'Satellite'):
relation = rnode.relation
elif (lnode.prop == 'Satellite') and (rnode.prop == 'Nucleus'):
relation = lnode.relation
else:
print('lnode.prop = {}, lnode.edu_span = {}'.format(lnode.prop, lnode.edu_span))
print('rnode.prop = {}, lnode.edu_span = {}'.format(rnode.prop, rnode.edu_span))
raise ValueError("Error when find relation for new node")
return relation

isn't it?
