Executes code in the Sandbox using the appropriate language runtime.

Arguments:

code str - Code to execute.

Raises:

DaytonaError - If the PTY session doesn’t exist or cannot be killed.

Example:

# Resize a PTY session to a larger terminal
new_size = PtySize(rows=40, cols=150)
updated_info = sandbox.process.resize_pty_session("my-session", new_size)

print(f"Terminal resized to {updated_info.cols}x{updated_info.rows}")
