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.comp_iter()。
def com_comp_iter(self, node): assert node[0] == symbol.comp_iter return node[1]
def com_generator_expression(self, expr, node): # comp_iter: comp_for | comp_if # comp_for: 'for' exprlist 'in' test [comp_iter] # comp_if: 'if' test [comp_iter] lineno = node[1][2] fors = [] while node: t = node[1][1] if t == 'for': assignNode = self.com_assign(node[2], OP_ASSIGN) genNode = self.com_node(node[4]) newfor = GenExprFor(assignNode, genNode, [], lineno=node[1][2]) fors.append(newfor) if (len(node)) == 5: node = None else: node = self.com_comp_iter(node[5]) elif t == 'if': test = self.com_node(node[2]) newif = GenExprIf(test, lineno=node[1][2]) newfor.ifs.append(newif) if len(node) == 3: node = None else: node = self.com_comp_iter(node[3]) else: raise SyntaxError, \ ("unexpected generator expression element: %s %d" % (node, lineno)) fors[0].is_outmost = True return GenExpr(GenExprInner(expr, fors), lineno=lineno)
