Hi Miki,
Thanks.. Creating two subprocesses worked for me. I did the code as below,

p = subprocess.Popen("echo t |", shell=True, stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
p1 = subprocess.Popen(["svn.exe", "list", "Https://127.0.0.1:443/svn/Repos"], shell=True, stdin=p.stdout, stdout=subprocess.PIPE, stderr=subprocess.PIPE).communicate()
output = p1[0]

Thanks again... :)
