Python: Print all files under a path

To print all the files under a path, we can do this with the Find command (find path-type f). Now I'm using Python's recursive return to implement this function.

[Email protected] ~]# vim print_files.py

#!/usr/bin/python

Import OS

Import Sys

def print_files (path):

Lsdir = Os.listdir (path)

dirs = [i-I in Lsdir if Os.path.isdir (Os.path.join (path,i))]

Files = [i-I in Lsdir if Os.path.isfile (Os.path.join (path,i))]

If files:

For f in Files:

Print Os.path.join (path,f)

If dirs:

For D in dirs:

Print_files (Os.path.join (path,d))

Print_files (Sys.argv[1])

Test:

We print all directories and files under the/etc/directory, with the following effects:

[email protected] ~]# python print_files.py/etc/

650) this.width=650; "src=" Http://s3.51cto.com/wyfs02/M02/80/19/wKiom1c3PRLgVG1rAAA6GmB9uug525.png "title=" Qq20160514225704.png "alt=" Wkiom1c3prlgvg1raaa6gmb9uug525.png "/>

Method Description:

Os.listdir: OS module method, print all the files in the directory, as a list, can be used after the list rewrite: [I for I in Lsdir]

Os.path.isdir: The Os.path method, which returns a Boolean value, determines whether a directory is behind.

Os.path.isfile: Os.path The method below, the return is also a Boolean value, judging behind is not a file.

Os.path.join: Os.path The method, connect the file path. Os.path.join (path,i):/etc/i

SYS.ARGV: sys module , which is used to get command-line arguments, Sys.argv[0] represents the file path of the code itself, in this case:

Sys.argv[0]------- Print_files . PY

SYS.ARGV[1]-------Path

Logical thinking:

(1) First list all files under the path

(2) Filter catalogue

(3) Filter files

(4) Determine whether there are files in the directory, if any, print out the file

(5) Determine whether there are subdirectories under the directory, if any, through recursion and then traverse the subdirectories of the file or directory.
