这个加的w是什么意思呐

自己解决了

老师，我是按照视频一步一步敲的，为什么报错了？

显示是版本问题，然后我这样升级了一下，显示安装的路径是C盘，难道是需要创建的项目在这个路径吗c:\program files\python36\lib\site-packages (19.3.1)

按装不了啊，尝试了python -m pip install --upgrade pip更新之后继续输入pip install pygame 就会这样

问题: 怎么总是提示我输入的三对双引号有问题呢? 这个输入有什么诀窍吗? 不就是Enter 键旁边的引号键 分别按三次吗? 为什么原始代码里面的正确的, 自己的总是提示错误呢?

老师  为啥我写完后敌方子弹碰到我方坦克后整个画面就卡住不动了呢，也不报错

老师我的window为什么一直是none

老师 这儿为什么有两个lines 代表什么

老师，请问一下这是什么原因，引用了还是报错

老师，这个有点不明白，难道__str__自动会执行？？

这个问什么报错了？

#coding=utf-8
import os

def getAllFiles(path,level):
    all_files = os.listdir(path)
    for filepath in all_files:
        # filepath = os.path.join(path,file)
        print("\t" * level + filepath)
        if os.path.isdir(filepath):
            getAllFiles(filepath,level+1)

getAllFiles(os.getcwd(),0)

这段代码有什么问题吗？为什么输出不了更下一层的文件啊？

如果稍微改动一下，把注释部分取消注释则可以正常输出全部内容，这是什么情况？
