Как вызвать def python из другого python файла

Question

Привет, у меня есть Python скрипт pruebas.py и я бы хотел вызвать другой python скрипт, который на самом деле является Flask (API). звук проводной, но во избежание проблем с CORS он запускается на серверной стороне (где работает), и я могу извлечь его из внешнего API.

Это код для файла, который извлекает данные из API externa:

import json, hmac, hashlib, time, requests, base64
from requests.auth import AuthBase

API_KEY = "xxxxxxxxxxxxxx"
API_SECRET = "xxxxxxxxxxxxxxxxxxxx"
API_PASS = "xxxxxxxxxxxxxxxxxxxxxxxxxx"

# Create custom authentication for Exchange
class CoinbaseExchangeAuth(AuthBase):
    def __init__(self, api_key, secret_key, passphrase):
        self.api_key = api_key
        self.secret_key = secret_key
        self.passphrase = passphrase

    def __call__(self, request):
        timestamp = str(time.time())
        message = timestamp + request.method + request.path_url + (request.body or b'').decode()
        hmac_key = base64.b64decode(self.secret_key)
        signature = hmac.new(hmac_key, message.encode(), hashlib.sha256)
        signature_b64 = base64.b64encode(signature.digest()).decode()

        request.headers.update({
            'CB-ACCESS-SIGN': signature_b64,
            'CB-ACCESS-TIMESTAMP': timestamp,
            'CB-ACCESS-KEY': self.api_key,
            'CB-ACCESS-PASSPHRASE': self.passphrase,
            'Content-Type': 'application/json'
        })
        return request

api_url = 'https://api.pro.coinbase.com/'

auth = CoinbaseExchangeAuth(API_KEY, API_SECRET, API_PASS)

r = requests.get(api_url + 'accounts/', auth=auth)
#print(json.dumps(r.json(), indent=2, sort_keys=True))

Код моего flask:

#import sumTwoNumbers
import pruebas
from flask import Flask, request
from flask_restful import Resource, Api

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

#class sumNumbers(Resource):
#    def get(self, first_number, second_number):
#        return {'data': sumTwoNumbers.sumTwo(first_number,second_number)}

class gdd(Resource):
    def get(self):
        return {'data': gdd.requests.get(api_url + 'accounts/', auth=auth)}

api.add_resource(gdd, '/gdd/')

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

Спасибо за любую помощь и извините, я не разработчик.

Цель - вызвать мой flask API, который будет получить информацию из внешнего API.

Я получаю эту ошибку:

Answer 1

Похоже, что вы хотите:

Заменить

gdd.requests.get(api_url + 'accounts/', auth=auth)

на:

import requests    

requests.get(api_url + 'accounts/', auth=auth)

Возможно, вы, возможно, еще не обращались к Flask -Restful и не запрашивает документацию, поэтому я вставлю их ссылки сюда и рекомендую вам взглянуть на это.
