i can not images using cv2.imwrite () method

Question

I want to copy all the pictures from one folder to another folder. I tried to run this code again and again but it returns me False only instead of saving pictures to other folder.

import cv2
import glob
input_path = 'C:\\Users\\Kazmi-PC\\OneDrive\\Pictures\\1\\*.*'
output_path = 'C:\\Users\\Kazmi-PC\\OneDrive\\Pictures\\2\\*.jpg'
for file in glob.glob(input_path):
   print("printing.....")
   print(file)
   a= cv2.imread(file)
cv2.imwrite(output_path, a)

you can't use * in output. You have to run imwrite inside for loop. And you have to use real, unique name for every file. — furas

if you want to copy files then you can use shutil.copy(input_name, output_name) but you still have to copy every file separatelly. But you can use directory as output and then it will use filename from input. — furas

You can't use * in output filename. You would have to use imwrite inside for loop and use unique filenames in output.

You can use shutil.copy(file, directory) to copy. So you can use output without *.jpg and you don't have to add filename in output.

But you still need to copy every file separatelly.

import glob
import shutil

input_path = 'C:\\Users\\Kazmi-PC\\OneDrive\\Pictures\\1\\*.*'
output_dir = 'C:\\Users\\Kazmi-PC\\OneDrive\\Pictures\\2\\'

for file in glob.glob(input_path):
   shutil.copy(file, output_dir)
