/ 13 мая 2018

Мне удалось собрать некоторые данные с динамического веб-сайта, и мои выходные данные представлены в формате json с единственным значением. Как изменить этот код, чтобы получить формат ключа и значения json и записать в файл с помощью python 

import requests
import json

with requests.Session() as s:
s.headers={"User-Agent":"Mozilla/5.0"}
s.headers.update({'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'})
res = s.post(URL, data = payload)

for data in res.json()['data']:

    brndname = data['brand_name']
    clssification = data['classification_name']
    common_name = data['common_name']
    dosage_form = data['dosage_form']
    expiry_date = data['expiry_date']
    manufacturer = data['manufacturer']
    manufacturer_country = data['manufacturer_country']
    product_strength = data['product_strength']
    registrant = data['registrant']
    registrant_country = data['registrant_country']
    output = (dataserial,certno,brndname,clssification,

   data = {'brandname':brndname, 'cerficate_number':certno,'expiry_date':expiry_date,'product_strength':product_strength}
    output = json.dumps(data, ensure_ascii=True, sort_keys=True)


    with open('drugs.json', 'w') as file:
        json.dump(output, file)
        file.write('file')
        file.close()

Вот вывод, который мне удалось получить снимок экрана , но пример того, что мне нужно, в следующем формате 

{
 "brand_name":"Supirocin"
 "certificate_no":"TAN 00,1820 D01A GLE"
 "classification_name":"Human Medicinal Products"
 "common_name":"Mupirocin"
 "dosage_form":"Ointment"
 "expiry_date":"22-06-2018"
 "id":"18345"
 "manufacturer":"Glenmark Pharmaceuticals Limited"
 "manufacturer_country":"INDIA"
 "no":"6"
 "product_strength":"2 %w/w"
 "registrant":"Glenmark Pharmaceuticals Limited"
 "registrant_country":"INDIA"
 }

Сначала вы создаете словарь, а затем конвертируете его в JSON. Например: 

name ='ali'
family='shahabi'
output={'name' :name ,'family': family}
json.dumps(output)

print: 

'{"name": "ali", "family": "shahabi"}'

Я предлагаю преобразовать: 

output = (dataserial,certno,brndname,clssification, common_name,dosage_form,expiry_date,m anufacturer, manufacturer_country, product_strength,registrant,registrant_country)

до 

output = {'dataserial':dataserial,'certno':certno,'brndname':brndname , ....}
...
