How to create a file list of my files included in the same folder?

Question

I have a folder which contains numpy files. I need to create a numpy list where I will put all my numpy file names. For that, I use this code:

import os

a = open('C:\\Users\\user\\My_Test_Traces\\Traces.list_npy', "w")
for path, subdirs, files in os.walk(r'C:\\Users\\user\\CPA_test_1000_Tests\\test'):
   for filename in files:
      f = os.path.join(path, filename)
      a.write(str(f) + os.linesep)

As a result, it gives me a list of my files and their paths like this:

   C:\\Users\\user\\My_Test_Traces\\ Trace1_Pltx1

   C:\\Users\\user\\My_Test_Traces\\ Trace2_Pltx2

   C:\\Users\\user\\My_Test_Traces\\ Trace3_Pltx3

   C:\\Users\\user\\My_Test_Traces\\ Trace4_Pltx4

however , I need only the files name, I don't need any spaces between lines:

   Trace1_Pltx1
   Trace2_Pltx2
   Trace3_Pltx3
   Trace4_Pltx4

then why are you joining with the `path`? The `filename` must be what you want to have. — Ma0, Mar 20 '17 at 10:55

There is a function tyhat is doing exactly what you need, you should try this:

os.path.basename(path)

You can use,

from os.path import basename
print basename('path/file.txt')

If you don't want extension, refer the post

Maybe this is better:

import os

folder = 'C:\\Users\\user\\CPA_test_1000_Tests\\test'

with open('C:\\Users\\user\\My_Test_Traces\\Traces.list_npy', 'w') as fp:
    fp.write(os.linesep.join(os.listdir(folder)))

what about the spaces between lines please, how to delete it? – Mar 20 '17 at 12:00
I didn't get any space on my environment. Can you close the file Traces.list_npy and open again? – Ke Li Mar 20 '17 at 12:09
I have my spaces in all between each line – Mar 20 '17 at 12:13
I use winPython version 3.6, it may be differs between versions of python. – Mar 20 '17 at 13:44
