Copy Files by getting name from text file. - Python

Question

I am trying to copy few files from one folder to another by reading names of files from a text file "input.txt". What did I do wrong? Thank you in advance.

import shutil
import os
f = open('input.txt','r')
src=r'C:\Users\abhishekcho\Desktop\Self\folder1'
dst=r'C:\Users\abhishekcho\Desktop\Self\folder2'

for i in range(4):
    file_name = f.readline()
    source = os.path.join(src,file_name)
    shutil.copy2(source,dst)

---

Output:

PS C:\Users\abhishekcho\Desktop\Self> &
C:/Users/abhishekcho/AppData/Local/Programs/Python/Python37-32/python.exe
c:/Users/abhishekcho/Desktop/Self/test.py Traceback (most recent call

Seems as if the trailing newline character \\n was included in your path and caused the error. You can remove it with rstrip()

import shutil
import os
f = open('input.txt','r')
src=r'C:\Users\abhishekcho\Desktop\Self\folder1'
dst=r'C:\Users\abhishekcho\Desktop\Self\folder2'

for i in range(4):
    file_name = f.readline().rstrip()
    source = os.path.join(src,file_name)
    shutil.copy2(source,dst)
