Creating a basic web page to trigger a Python script
Question
I have a Python script that loops through a list of SQL queries read from an Excel file, executes them, and stores output results to a .csv file.
Currently I trigger this from the command line locally. I would like to create a very basic Web page, something that basically has a button to click to execute the Python script for now. If I can get the output file stored there somehow as well, even better.
The idea being I would start with it locally, but then move the web page somewhere where my team could access it and do the same thing.
I don't need much functionality at all for this web page obviously but this stuff is new to me so not quite sure where to start. Any ideas?
Thanks

I guess Flask would be a decent choice for a simple web app.
folder structure:
├── app.py
├── static
│ ├── index.html
app.py ( EDIT added index.html route handling, duh doy)
from flask import Flask
app = Flask(__name__, static_url_path='', template_folder='static')
@app.route('/')
def index():
return app.send_static('index.html')
@app.route('/execute')
def execute_sql_logic():
# Do stuff here
return 'SQL executed', 200
if __name__ == '__main__':
app.run()
You'll need to export FLASK_APP=app.py in your working directory
index.html
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <a href='/execute'><button>execute SQL</button></a> </body> </html>
Simplest example I could think of.
Now when you'll run app.py and navigate to localhost:5000 (Port defaults to 5000 if I remember correctly) you'll see the HTML page with the execute SQL button. Clicking on it will send a GET to localhost:5000/execute which in turn will call your function.
Deploying on a server is beyond the scope of this answer unfortunately.
