File creating with question mark quffix

[pythonbabe]

Hi All,

Expectation is to get a file as "pre.hostname" if doesn't exist in current directory but i am getting "pre.hostname?" instead.
Can someone correct me?

I am using python-3.3.1 on RHEL 7 OS

import subprocess
from subprocess import check_output
import os
import os.path

cur_dir = os.getcwd()
#pwd = check_output("pwd", shell=True).decode()
hostname = check_output("hostname", shell=True).decode()
pre = ("/pre.")
post = ("/post.")

print ()
print ("Current Directory :", cur_dir)

fname = (cur_dir+pre+hostname)
print ("Checking the existence of File", fname)
if os.path.isfile(fname):
   print ("File Exists")
else:
   print ("File Doesn't exist; Creating a new one")
   file1 = open(fname, "w").close()

On my computer, the string returned by check_ouptut("hostname", shell=True) has a newline at the end of the line. Combined with the decode this may be the issue. You can try this

hostname = check_ouptut(['hostname']).strip().decode()

Your code worked. Thank you Gribouillis.
