Specific operation methods:

1. First of all, you need to import the os module in the python script for file operation.

Import os

2, through the for loop statement to determine whether the directory is a folder, if it is a file, print, otherwise it will be re-judged, so as to achieve traversal operation.

The code example is as follows:

Import os # Import os module

Def bianLi (rootDir): # parameters passed in

For root,dirs,files in os.walk (rootDir): # use API to quickly classify paths in a directory

For file in files: # print out the file with a for loop

Print (os.path.join (root,file))

For dir in dirs: # use the for loop to traverse the folder again

BianLi (dir)

RootDir = "/ home/du/1" # specify a folder to start traversing

BianLi (rootDir)
