Question

Python

Write the list of all the files in the directory ptest_0 , in a text file contents.txt (this file already exists there.) in separate lines.

1)

import glob
import shutil
import os

Beginning_folder = r"/home/MikeyV/Laptop/test_0/learn0_0";

Last_folder = "/home/MikeyV/Laptop/ptest_0";
try:
   os.makedirs(last_folder);

except;
   print"Folder already exists...";
for txt _file in glob.glob(beginning_folder+"\\*txt"):
   Shuril.copy2(txt_file,last_folder);

Answer 1

The requirement according to the problem is for a given path of directory we have to get the list of all files in that directory and save the list of all files in the directory into a contents.txt file.

from os import listdir
from os.path import isfile, join

# Below I define the path to directory in which I have to get the list

dir_path="E:\\python\\test"
# above I have taken a sample path of my own directory you
# replace it with the you own required path of directory

try:
#Getting list of all file in given location
onlyfiles = [f for f in listdir(dir_path) if isfile(join(dir_path, f))]
# opening the contents.txt file and write each file in list in one
# single line in the file
with open('contents.txt','w') as fp:
for i in onlyfiles:
fp.write(i+'\n')
except FileNotFoundError as e:
print(e)

The above picture shows the different files in the test directory which I used in the program code

The contents.txt file which contains output image is shown below

I have not used some library which is said in sample code you have given because we can write code to the question given without using them easily without any problem and it still easy and fast than that.

I hope you got the answer and understand it.

Thank You:):)
