《笨方法学PYTHON》——thirdteenthlesson

习题26：恭喜你，现在可以考试了！

这道题是说，他将习题24和25的代码胡乱改了一下，然后让我们将它改对，稍微看了一下。。。都是一些语法错误。。。还是那句话，现在IDE那么发达，你写错，直接给你提示了，除非你视而不见，要不然写出来的代码不可能存在语法错误的。好了，我把作者的错误代码放出来，有兴趣的可以改一下，python2和python3区别的方法我提前改好

之前说过IDE的代码格式化快捷键是ctrl+shift+L，使用后就变成这个样子了.......明显嘛，def后面少了:

个人觉得，这道题的意义不大，还是那句话，工具是越来越强大了，很多之前人必须熟记的东西，现在工具都帮忙做了。所以语法错误，根本没必要那么重视，IDE都会有提示，给了提示会改就成，不熟的童鞋可以试着改改。

下一道习题开始讲逻辑了，这一篇就写这么多吧，over

print_r('点个赞吧')；
var_dump('点个赞吧')；
NSLog(@"点个赞吧！")
System.out.println("点个赞吧!");
console.log("点个赞吧!");
print("点个赞吧!");
printf("点个赞吧!\n");
cout << "点个赞吧!" << endl;
Console.WriteLine("点个赞吧!");
fmt.Println("点个赞吧!")
Response.Write("点个赞吧")；
alert（’点个赞吧’）
