ptyprocess

Warnings

• gotcha Not all subprocesses behave the same in a pseudo terminal.
  Fix: Test subprocess compatibility before production use.
• deprecated Older methods of invoking processes may not fully utilize the pty.
  Fix: Update your method calls to the new standardized approach.

Install

• pip install ptyprocess Install ptyprocess

Imports

• PTYProcess

  from ptyprocess import PTYProcess

  Common mistake is to use 'import ptyprocess' instead, which doesn't expose the PTYProcess class directly.

Quickstart

This quickstart launches a subprocess to list files in the current directory.

import os
from ptyprocess import PTYProcess

proc = PTYProcess.spawn(['ls', '-l'])
print(proc.read())
