Nice job, Sir!

Hi I believe that your statistics are wrong! A lot of people became legendary grandmasters today for no reason and no one knows it why, maybe Magic? At least 10% is legendary grandmaster today.

I hate pupils

My Python 3 code to do queries:

import requests, hashlib, time, random, string, urllib, collections, json
import pickle, os.path
import sys, time
from time import sleep

class CFApi:
	key = 'ApiKey'
	secret = 'ApiSecret'
	apiurl = '//codeforces.com/api/'

	def CreateUrl(method, parameters = {}):
		seed = ''.join(random.choice(string.ascii_lowercase) for x in range(6))
		parameters['apiKey'] = CFApi.key
		parameters['time'] = str(int(time.time()))
		parameters['lang'] = 'en'
		param = collections.OrderedDict(sorted(parameters.items()))
		parameters['apiSig'] = seed + hashlib.sha512((seed+'/'+method + '?' + urllib.parse.urlencode(param)+'#'+CFApi.secret).encode()).hexdigest()
		return CFApi.apiurl + method + '?' + urllib.parse.urlencode(parameters)

	def GetJsonResult(method, parameters={}):
		try:
			t = (requests.get(CFApi.CreateUrl(method, parameters))).json()
			CFApi.lastcall = time.time()
			if t['status']!='OK':
				print(t)
				return None
			r = t['result']
			return r
		except Exception as e:
			print('{}: {}'.format(e.__class__.__name__, e), file=sys.stderr)
#Usage:
contests = CFApi.GetJsonResult('contest.list', {'gym': 'false'})
