Python: Print Statements Aren't Working!

1 
from flask import Flask, request, jsonify
from waitress import serve
import requests
import time
import threading

app = Flask(__name__)

# Main entry point
if __name__ == '__main__':
    print("Hello World")
    # threading.Thread(target=check_model_status).start()
    serve(app, host="0.0.0.0", port=8080)

"I'm running this simple code to generate Hello World, but it's not showing up in my logs...
Help?

Also, I'm using Dockerfile, don't know if it's related to all of this.."

Hey,

The initial discrepancy I spotted is that “main” should be replaced with “name” in your initialization code.

It’s possible that the output of your print statements is being buffered, causing them to group multiple statements before they’re displayed or written to a file. To address this, you might want to flush the output buffer manually. You can do this by adding the flush=True argument to your print function, like so: print("Your message", flush=True).

Thank you Jeremy for your support.

I’ve changed my code to this

from flask import Flask, request, jsonify
from waitress import serve
import requests
import time
import threading

app = Flask(__name__)

# Main entry point
if __name__ == '__main__':
    print("Hello World", flush=True)
    # threading.Thread(target=check_model_status).start()
    serve(app, host="0.0.0.0", port=8080)

and also I’ve cleaned the cache and deployed the new code.

Here are my logs:

As you can see no printing of Hello World, I don’t know what’s the mistake I’m making…

5

I’ve changed the code, added flush=True, but still no printing of the message.

6

Here’s my code:

from flask import Flask, request, jsonify
from waitress import serve
import requests
import time
import threading

app = Flask(__name__)

# Main entry point
if __name__ == '__name__':
    print("Hello World", flush=True)
    # threading.Thread(target=check_model_status).start()
    serve(app, host="0.0.0.0", port=8080)
7

And here are the logs:

Hey,

I tested it in both Python and Docker environments and couldn’t replicate the issue, suggesting our side is clear. The hiccup might stem from the ‘waitress’ package you’re utilizing, though I can’t say for certain. Is there a specific reason you’re aiming to print something at this juncture in your app? Perhaps try inserting a print statement in different sections of your code to see if that makes a difference?

Found the solution for my case for anyone in the future.

import logging

app = Flask(name)

And use

app.logger.info(“Your Message”)
