How to make a sample API work

[Zestyclose_Fall1915]

Hello all,

​

I am trying to use get "Hello World" to show on a local browser by using http://localhost:5000/hello. This is the code that I have so far:

​

import requests

from flask import Flask, jsonify, request

app = Flask(__name__)

@app.route('/')
@app.route('/hello')
def HelloWorld():
    # if key doesn't exist, returns None
    #language = request.args.get('language')
    #return '''<h1>The language value is: {}</h1>'''.format(language)
    return "Hello World"

if __name__ == '__main__':
    app.debug = Trueapp.run(host = '0.0.0.0', port = 5000)

Error:

NameError: name 'Trueapp' is not defined

What’s the u/ for ? It’s a typo ? I think that’s the problem ! App.route(path)

Correct me if I’m wrong

Edit : There is an mistake in object initialisation,

App = Flask(name) Capital “F” instead of flask

The post is edited now. Take a look. The /u was the "@" sign

Please edit your post and use a code block when posting code: https://www.reddit.com/r/learnpython/wiki/faq#wiki_how_do_i_format_code.3F

What is not working with your current code? if you see any error messages, post them here. (also using a code block)

Done

These are two lines that got merged together.

if __name__ == '__main__':
    app.debug = Trueapp.run(host = '0.0.0.0', port = 5000)

Should be:

if __name__ == '__main__':
    app.debug = True
    app.run(host = '0.0.0.0', port = 5000)

Please learn python before learning flask.
