我们从Python开源项目中，提取了以下10个代码示例，用于说明如何使用symbol.factor()。
def factor(self, nodelist): elt = nodelist[0] t = elt[0] node = self.lookup_node(nodelist[-1])(nodelist[-1][1:]) # need to handle (unary op)constant here... if t == token.PLUS: return UnaryAdd(node, lineno=elt[2]) elif t == token.MINUS: return UnarySub(node, lineno=elt[2]) elif t == token.TILDE: node = Invert(node, lineno=elt[2]) return node
def power(self, nodelist): # power: atom trailer* ('**' factor)* node = self.com_node(nodelist[0]) for i in range(1, len(nodelist)): elt = nodelist[i] if elt[0] == token.DOUBLESTAR: return Power([node, self.com_node(nodelist[i+1])], lineno=elt[2]) node = self.com_apply_trailer(node, elt) return node
