Copy certain files to other folder using Python ( File Management in Python )

Question

I want to check a folder and all subfolders if a certain file exists. If exists then I want to copy that in another folder. I have tried the following stuff

def copy_files(src, dest):
    files = os.listdir(src)
    for f in files:
        shutil.copy(src +f , dest)

for root, dirs, files in os.walk(my_path):
    for f in files:
        if f.endswith(".7z"):
            print("found files: " , f)
            copy_files(my_path, arch_dest)

On the copy_files function works. But it does not work inside the for the loop.

I am getting the following error:

Permission denied: './data/f_1'

What am I doing wrong?

The Copy function works in other folders. But in this loop, it does not work. I need to make it work inside the loop.

Update:

I am assuming the problem is more with the path, I have checked inside the for loop it shows the home directory where it is. with print(os.getcwd())

Do I need to then go to the folder while checking the file?

Either run the script with sudo or from a shell that was started 'as administrator'? — meissner_

Found the solution finally. I knew it in is because of the Root/Path. It has nothing to do with admin/sudo stuff.

It can be done as follows.

for r,d,files in os.walk(my_path):
    for f in files:
        print(r)
        shutil.copy(r + "/" + f, dest_path)

You need to run your python script as sudo user

e.g. sudo python filename.py

Try using a try/except around the loop to ignore the files you dont have permission to search:

try:
    for root, dirs, files in os.walk(my_path):
        for f in files:
            if f.endswith(".7z"):
                print("found files: " , f)
                copy_files(my_path, arch_dest)
except OSError:
    pass

Is ./data/f_1 a destination or a file to be copied?

TheTechGuy Over a year ago

The files from the folder

TheTechGuy Over a year ago

The root folder has more directories. The code needs to check each folder and find the file

jc1850 Over a year ago

Does the traceback say anything else like which line is causing the error?

Thought it might not, so for some reason you dont have permission to do something to the file, do you know which line is causing the issue? Is it the os.walk(my_path) call?
