Python Forum

Hi, first of all I'm new here so hello everyone! I have an issue. I'm trying to learn how to work with a specific API and I need JSON to do it. I used pip to install simplejson, but this didn't allow my code to work. So I then used pip to install json, or tried, but I keep getting a failure in command prompt (I'm on Windows).

C:\Users\spect>pip install json
Collecting json
  Using cached json-99.0.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "C:\Users\spect\AppData\Local\Temp\pip-build-tfkprp8j\json\setup.py", line 2, in <module>
        raise RuntimeError("Package 'json' must not be downloaded from pypi")
    RuntimeError: Package 'json' must not be downloaded from pypi

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in C:\Users\spect\AppData\Local\Temp\pip-build-tfkprp8j\json\

It's obvious to me what the issue is, pypi, but I don't really know how to install anything in python except using pip.

json is apart of the standard library
https://docs.python.org/3/library/json.html

You are going to need to be more specific on how your code did not work.

json is a built-in module, you don't need to install it with pip.

For working with API is Requests very good,
it can do the job of build in of json and urllib in an easier way.

Well, here's my code, I just get an:

Error:
{'error': 'not found'}

as a reponse.

import urllib.parse
import requests

main_api = 'https://api.guildwars2.com/v2/achievements'

address = 'achievements'
url = main_api + urllib.parse.urlencode({'address': address})

json_data = requests.get(url).json()
print(json_data)

---

I just figured out it wasn't the code that wasn't working, it was a typo in the way the API processes requests. Well, step one down. Many more to go. Sorry about the flacid question guys.

That website doesnt show a hash table at all, but a list.

You are making wrong API call,also missing achievements/
But if fix that still not work.

>>> import urllib.parse
... import requests
...
... main_api = 'https://api.guildwars2.com/v2/achievements/'
... url = main_api + urllib.parse.urlencode({'address': address})
... json_data = requests.get(url).json()
...  print(json_data)
{'text': 'no such id'}

Doc for API
Just to make a link that work.

>>> import urllib.parse
... import requests
... from pprint import pprint
...
... main_api = 'https://api.guildwars2.com/v2/achievements/'
... url = main_api + urllib.parse.urlencode({'1?lang': 'en'})
... json_data = requests.get(url).json()
... pprint(json_data)

                                       

Output:
{'description': 'A few more centaur herds are thinned out.', 
 'flags': ['Permanent'],                                     
 'id': 1,                                                    
 'locked_text': '',                                          
 'name': 'Centaur Slayer',                                   
 'requirement': 'Kill  centaurs.',                           
 'tiers': [{'count': 10, 'points': 1},                       
           {'count': 100, 'points': 5},                      
           {'count': 500, 'points': 5},                      
           {'count': 1000, 'points': 5}],                    
 'type': 'Default'}                                          

>>> json_data['description']
'A few more centaur herds are thinned out.'

Thanks snippsat. I'm going to read the urllib documentation so I don't do this mistake again. Got it working, so I appreciate all you guys' help!
