flask 'hello world' not working
I don't know why but when I change
app.run()to
app.run(port=4996)it starts working. No idea why the default port is throwing an error. Oh well.
from flask import Flaskapp = Flask(__name__)@app.route('/')def index(): return 'Hello World'if __name__ == '__name__': app.run()app.run(port=5000)
For Windows machines you can use the command in cmd:
set FLASK_APP=python_file.pyflask run
