Python _ast 模块，IfExp() 实例源码

我们从Python开源项目中，提取了以下5个代码示例，用于说明如何使用_ast.IfExp()。

            assert len(then) == 1
            then = then[0]

            assert len(else_) == 1

            else_ = else_[0]

            if_exp = _ast.IfExp(test, then, else_, lineno=node.lineno, col_offset=0)
            return if_exp
        else:
            return node
