Asked By – Robert Filter
I would like to simply print a “hello world” to the python console after /button is called by the user.
This is my naive approach:
@app.route('/button/') def button_clicked(): print 'Hello world!' return redirect('/')
Background: I would like to execute other python commands from flask (not shell). “print” should be the easiest case.
I believe I have not understood a basic twist here.
Thanks in advance!
Now we will see solution for issue: How to print from Flask @app.route to python console
An easy way to do this is by printing to stderr. You can do that like this:
from __future__ import print_function # In python 2.7 import sys @app.route('/button/') def button_clicked(): print('Hello world!', file=sys.stderr) return redirect('/')
Flask will display things printed to stderr in the console. For other ways of printing to stderr, see this stackoverflow post
