Move files from one directory to another if they appear in a text file in Python (take 2)

Question

Ok I'm going to try this again, apologies for my poor effort in my pervious question.

I am writing a program in Java and I wanted to move some files from one directory to another based on whether they appear in a list. I could do it manually but there a thousands of files in the directory so it would be an arduous task and I need to repeat it several times! I tried to do it in Java but because I am using Java it appears I cannot use java.nio, and I am not allowed to use external libraries.

So I have tried to write something in python.

import os
import shutil

with open('files.txt', 'r') as f:
    myNames = [line.strip() for line in f]
    print myNames

dir_src = "trainfile"
dir_dst = "train" 
for file in os.listdir(dir_src):
    print file  # testing
    src_file = os.path.join(dir_src, file)
    dst_file = os.path.join(dir_dst, file)
    shutil.move(src_file, dst_file)

"files.txt" is in the format:

a.txt
edfs.txt
fdgdsf.txt

and so on.

So at the moment it is moving everything from train to trainfile, but I need to only move files if the are in the myNames list.

Does anyone have any suggestions?

Answer 1

check whether the file name exists in the myNames list put it before shutil.move

if file in myNames:
