Automate a Python REPL Session

Problem Description

Your team is building a CI pipeline that validates a Python utility module by interactively running it inside a Python REPL session. The goal is to automate a sequence of steps: launch Python, import the module, call a function, print the result, and confirm the output is correct — all without any human at the keyboard.

The utility module is simple: it exposes a function add(a, b) that returns the sum of two numbers. You need to write a shell script (named run_session.sh) that uses virtui to drive this entire interaction. The script should launch a Python REPL, execute the sequence of REPL commands to import and test the module, capture the output, and clean up properly when done. After running, the script should write a summary of what it observed (the final screen output) to a file named session_output.txt.

Output Specification

• run_session.sh — an executable shell script that drives the virtui session
• session_output.txt — a text file containing the captured screen output from the REPL session showing the result of the add call
• module.py — the Python file containing the add(a, b) function that is tested

The script should be self-contained: running bash run_session.sh from the same directory should execute the whole flow from daemon check through session cleanup.

Input Files

The following files are provided as inputs. Extract them before beginning.

=============== FILE: inputs/module.py =============== def add(a, b): return a + b

if name == "main": print(add(1, 2))
