reading content of a directory and its subdirectories with python

Question

i have directory path/to/dir that contains 10 subdirectories. there files in all of the subdirectories. I want to append these files in every subdirectory into a unique list. How can I do this?

Answer 1

What i understood is you just wanted to list all the filenames from a particular directory and its sub-directory.

list1=[] #Empty list

for root, dirs, files in os.walk(fr"path\\to\\directory", topdown=False): 
#Listing Directory
    for name in files:
        a=os.path.join(root, name)
        print(a)
        list1.append(a)
