Python: Need to add chosen filenames into an array

The idea is simple: there is a directory with 2 or more files *.txt. My script should look in the directory and get filenames in order to copy them (if they exist) over the network. As a Python newbie, I am facing problems which cannot resolve so far. My code:

files = os.listdir('c:\\Python34\\');
for f in files:
    if f.endswith(".txt"):
    print(f)

This example returns 3 files:

LICENSE.txt
NEWS.txt
README.txt

Now I need to use every filename in order to do a SCP. The problem is that when I try to get the first filename with:

print(f[0])

I am receiving just the first letters from each file in the list:

L
N
R

How to add filenames to an array in order to use them later as a array elements?

You can also try using the EXTEND method. So you say:

x = []
for f in files:
     if f endswith(".txt"):
           x.extend([f])

so it would be "adding" to the end of the list the file in which f is on.

If you want a list of matching files names, then instead of using os.listdir and filtering, use glob.glob with a suitable pattern.

import glob
files = glob.glob('C:\\python34\\*.txt')

Then you can access files[0] etc...

The array of files is files. In the loop, f is a single file name (a string) so f[x] gets the xth character of a filename. Do files[0] instead of f[0].
