In this tutorial, you'll be examining a couple of methods to get a list of files and folders in a directory with Python. You'll also use both methods to recursively list directory contents. Finally, you'll examine a situation that pits one method against
r or R starts a raw string, used to prevent escape sequences in the string (see “Escape with \” on page 66 and Chapter 12 for its use in string pattern matching). Then, there’s the combination fr (or FR, Fr, or fR) that starts a raw f-string. A u starts a Unicode string...
sys模块有一个argv变量,用list存储了命令行的所有参数。argv至少有一个元素,因为第一个参数永远是该.py文件的名称,例如: 运行python3 hello.py获得的sys.argv就是['hello.py']; 先解释什么是命令行参数。 $ Python --version Python2.7.6 这里的--version就是命令行参数。如果你使用Python --help可以看到更多...

在Python中有很多内建函数,比如前面已经讲到的type(), dir(), print(),int(),str(), list()等等,这些函数在安装好Python后就能立即使用。除了内建函数,我们也可以通过创建自定义函数来完成一些需要重复使用的代码块,提高工作效率。 3.4.1 函数的创建和调用 在Python中,我们使用def语句来自定义函数,def语句...
