老师什么是有限的?
mybatisdemo.rar
老师找不到在哪里错了我的jdk是1.8
ASN1.prototype.getHexStringValue = function () {
^
ReferenceError: ASN1 is not defined
解决方法window=globalThis,其他不该,我把其他改了,所以报了bitLength的错
还是不行,我的系统是64位的,python也是64位的,我重新配置了
老师,部署provide的时候启动一直报这个错误,还木有找到答案,端口占用吗?
public List<E> getGrandChildren(E item){ //存放所有子孙结点中的元素 List<E> list = new ArrayList<>(); //获取当前结点的子结点 List<E> child = this.getChild(item); if(child ==null)return list; //遍历子结点 for (int i =0;i<child.size();i++){ //获取节点中的元素 E ele = child.get(i); //递归 List<E> tem = this.getGrandChildren(ele); list.add(ele); list.addAll(tem); } return list; }
老师好,如果获取生物的子孙结点(植物,动物,菌类),当递归到动物结点时,会递归(脊椎动物,脊索动物 等),一直往下的子结点走,那么菌类什么时候递归?
这是哪有问题啊
老师,安装错版本了,但是不知道安装到那个位置了,怎么彻底删除呀,想重新安装
老师,我想问一下这个是什么问题啊?
元组的作用和数组的作用是一样的吗,用来定义和赋值吗
老师,下面两行代码运行时报的是如下的提示信息:
I:/百战卓越程序员培训之Python/第四阶段Python核心特性/第4阶段个人练习/函数式编程/test01_range的使用.py:32: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated, and in 3.8 it will stop working

我方坦克时,游戏界面停止了,并没有出现爆炸效果!

安装miniconda 使用完 conda init powershell 命令后重新启动就出现这种情况
这怎么解决呢?
n=0 sum=0 salarys=[] while True: m=input('请输入员工工资: ') if m.upper()=='Q': print('输入结束,谢谢') break if float(m)<0: continue n+=1 sum+=float(m) salarys.append(float(m)) print('员工人数{0}'.format(n)) print('工资明细:',salarys) print(sum) print('平均工资{1}'.format(sum/n))
一直提醒我报错了,但是找半天不知道哪里错了
