Python random File Reading

The Code is as follows:

Import osimport randomrootdir = "d :\\ face \ train" file_names = [] for parent, dirnames, filenames in OS. walk (rootdir): # three parameters: return 1. parent directory 2. all folder names (excluding paths) 3. all file names: file_names = filenames # for filename in filenames: # output file information # print ("parent is" + parent) # print ("filename is:" + filename) # print ("the full name of the file is:" + OS. path. join (parent, filename) x = random. randint (0, len (file_names)-1) print (file_names [x])

Note:

1. This Code passes the test on Python3.5

2. The rootdir parameter indicates the directory of the folder you want to traverse. Modify it according to your actual needs.
