Question

In python, rite 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.

Answer 1

Answer.

Step 1 Code:

import os

def readFile(filename):

withopen(filename, "r") as f:

for line in f:

print(line)

def displayFiles(pathname, d=1):

indent = ''

for i inrange(d):

indent = indent + ' '

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

for item in os.listdir(pathname):

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

print(indent + newItem)

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

displayFiles(newItem,d+1)

else:

print(indent + pathname)

readFile(pathname)

displayFiles("program.txt")
