Write a recursive function, displayFiles, that expects a pathname as an argument. The path name can be either the name of a file or the name of a directory. If the pathname refers to a file, its filepath is displayed, followed by its contents, like so: File name: file_path Lorem ipsum dolor sit amet, consectetur adipiscing elit ... Otherwise, if the pathname refers to a directory, the function is applied to each name in the directory, like so: Directory name: directory_path File name: file_path1 Lorem ipsum dolor sit amet ... File name: file_path2 Lorem ipsum dolor sit amet ... Test this function in a new program.

The following code will be used to write a recursive function and display files

Explanation:

#Import required packages

import os

#Define recursive function

#displayFiles () has a single argument

#which may be either pathname or filename

def displayFiles (pathname):

#if the given argument is pathname for directory

if (os. path. isdir (pathname)):

#open the directory

for item in os. listdir (pathname):

#append items in the list

newItem = os. path. join (pathname, item)

#print each filename

#call the function recursively

displayFiles (newItem)

#otherwise if the pathname

#is filename

else:

#set the pathname to filename

filename=pathname

baseFile = os. path. basename (filename)

print ("File Name: ", baseFile)

#open the file in read mode

with open (filename, "r") as file:

print ("Content:")

#display the contents of the file

for line in file:

#print line

print (line)

print ()
