flask_restful import Resource error

Question

I did the following tutorial on youtube: https://www.youtube.com/watch?v=s_ht4AKnWZg

This is my code:

from flask import Flask, request
from flask_restful import Resource, Api

app = Flask(__name__)
api = Api(app)

class HelloWorld(Resource):
    def get(self):
        return {'about':'Hello World!'}

    def post(self):
        some_json = request.get_json()
        return {'you sent': some_json}, 201

class Multi(Resource):
    def get(self, num):
        return {'result': num*10}

api.add_resource(HelloWorld, '/')
api.add_resource(Multi, '/multi/<int:num>')

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

Now when I run the script, I get following error:

/home/one/systemx/test_api$ python flask_restful.py
Traceback (most recent call last):
  File "flask_restful.py", line 2, in <module>
    from flask_restful import Resource, Api
  File "/home/one/systemx/test_api/flask_restful.py", line 2, in <module>
    from flask_restful import Resource, Api
ImportError: cannot import name Resource

The code is 1:1 like in the video. Does someone have a idea where the problem is?

Answer 1

As it was pointed out in the comments by @tobey, you need to rename your program to something else like app.py because python is trying to find flask_restful and it finds your program instead of the package.
