Hi all,

I want to list the repositories in svn using python. For this i have used below command,
" res = subprocess.check_output(["svn.exe", "list", "Https://127.0.0.1:443/svn/Repos"], stderr=subprocess.STDOUT) "

but it throws an exception, since it requires an user input to validate certificate,
" (R)eject, accept (t)emporarily or accept (p)ermanently? "

from Command prompt im able to pass the input while calling the process, and im able to get the output

"echo t | svn list Https://127.0.0.1:443/svn/Repos"

But i dont know how to pass the "echo t | " in subprocess.check_output while calling a process.
Is there a way to do this?
Please help.
