Add list item into executable command

[Gribouillis]

Use subprocess.run() (for python >= 3.5). It is simpler than os.system()

import os
import subprocess as sp
program = "C:\\Users\\cmueller\\Desktop\\test\\logs\\this.exe"

for dirlist in os.listdir():
    outfile = dirlist + '_end_dump'
    sp.run([program, '-E', dirlist, '-c', outfile])
