python subprocess bash ubuntu Python

I've hit a wall trying to I'm confused about After trying multiple solutions online, I still can't figure this out. I tried several approaches but none seem to work... I'm working with an scenario when trying to execute a shell script from a Python script using the `subprocess` module on my Ubuntu 22.04 system. My shell script is quite simple, and I verified that it works perfectly when executed directly from the terminal. Here’s the basic structure of my shell script `script.sh`: ```bash #!/bin/bash echo "Hello from the shell script!" ``` I made sure to give it executable permissions using `chmod +x script.sh`. However, when I try to run it from Python, it seems to run without any output: ```python import subprocess # Attempt to run the script def run_script(): process = subprocess.Popen(['./script.sh'], stdout=subprocess.PIPE, stderr=subprocess.PIPE) output, behavior = process.communicate() return output, behavior output, behavior = run_script() print(f'Output: {output.decode()}') print(f'behavior: {behavior.decode()}') ``` Despite the script being executed, I get no output, and the behavior message is empty as well. I also checked the return code from the process, which is 0, indicating success. I tried running the Python script in the same directory as the shell script, and I even used absolute paths, but nothing seems to work. I suspect it might be related to environment variables or the execution context. Any suggestions on what I might be missing or how to debug this scenario further? Thanks in advance! For context: I'm using Python on macOS. This is part of a larger REST API I'm building. I'm open to any suggestions. This is for a web app running on Ubuntu 22.04.
