[FIXED] Flask - 404 not found

Issue

I am a newbie in the flask development this is my first program in the flask but it shows me this error:

The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

& this is my code

from flask import Flask

app = Flask(__name__)


@app.route('/index')
def index():
    return 'Hello World'


if __name__ == '__main__':
    app.run(debug=True)

Solution

I think you should just go to http://localhost:5000/index or http://127.0.0.1:5000/index but if you want to make that page your code should be like that

from flask import Flask

app = Flask(__name__)


@app.route('/')
def index():
    return 'Hello World'


if __name__ == '__main__':
    app.run(debug=True)

change @app.route('/index') to @app.route('/') also you should check this http://flask.pocoo.org/docs/0.12/quickstart/#routing
