Hi Kushal,

I tried passing the value 't\n' to check_output. But I think we cannot pass a string to stdin.

When I tried the below command,
subprocess.check_output([svn, "list", repos_Url], stdin='t\n', stderr=subprocess.STDOUT)

I got the below error message,
  File "C:\Python27\lib\subprocess.py", line 786, in _get_handles
    p2cread = msvcrt.get_osfhandle(stdin.fileno())
AttributeError: 'str' object has no attribute 'fileno'

could you tell me how to pass the value to stdin..
