Check the root variable. You might be looking for the file at ./access_log-20150215 that is actually in a subdirectory such as ./subdir/access_log-20150215. If you want to explore all subdirectories use f=open(os.path.join(root,file),’r’) but if you only want the top directory you can use os.listdir(‘.’) 3 solved Python script looking for nonexistent file

Fix your code in your example and make your question more clear. That said, it’s unclear whether you’re trying to validate an uploaded file or a downloaded file.
