1 2 3 4 5 | import os for dirname, dirnames, filenames in os.walk('# I will have a directory here'): for filename in filenames: print (os.path.join(dirname, filename)) |
它的作用是在python中打印一些文件的目录。但除了我所知甚少…谢谢。。。还有其他一些页面有这个代码，但它没有在"假人指南"中完全解释。所以我有点困惑。感谢您的帮助……)
我试试看，希望能有所帮助。
1 2 3 4 5 6 7 | import os # vvvvvvv directory name of the current position in the walk (eg, /var then /var/log then /var/log/apache2, etc) # vvvvvvvv list (array) of sub directories # vvvvvvvvv list (array) of files for dirname, dirnames, filenames in os.walk('# I will have a directory here'): # loops through the directories list for filename in filenames: #loops through the files returned by the previous for loop print (os.path.join(dirname, filename)) # join the directory and the filename returning something like /var/log/dmesg.log |
