Theosmodule contains a long list of methods that deal with the filesystem, and the operating system. One of them iswalk(), which generates the filenames in a directory tree by walking the tree either top-down or bottom-up (with top-down being the default setting). os.walk()returns a...

Generate the file names in a directory tree by walking the tree either top-down or bottom-up. For each directory in the tree rooted at directory top (including top itself), it yields a 3-tuple (dirpath, dirnames,filenames)...每次能够得到一个三元tupple。当中第一个为起始路径,第二个为起...

使用Git 仓库包括以下步骤。首先,通过运行git init或git clone命令创建 Git 仓库。第二,你用git add <filename>命令添加文件让仓库跟踪。第三,一旦你添加了文件,你可以用git commit -am "<descriptive commit message>"命令提交它们。此时,您已经准备好对代码进行更多的更改了。
