title: Determine the rate limit for requests
body: <p>I have a question about rate limits. 
  I take a data from the CSV and enter it into the query and the output is stored in a list. 
  I get an error because I make too many requests at once.
  (I can only make 20 requests per second). How can I determine the rate limit?</p>
  
  <pre><code>import requests
  import pandas as pd 
  
  df = pd.read_csv("Data_1000.csv")
  list = []
  
  
  
  def requestSummonerData(summonerName, APIKey):
  
      URL = "https://euw1.api.riotgames.com/lol/summoner/v3/summoners/by-name/" + summonerName + "?api_key=" + APIKey
      response = requests.get(URL)
      return response.json()
  
  def main():
      APIKey = (str)(input('Copy and paste your API Key here: '))
  
      for index, row in df.iterrows():
          summonerName = row['Player_Name']
          responseJSON  = requestSummonerData(summonerName, APIKey)
          ID = responseJSON ['accountId']
          ID = int(ID)
          list.insert(index,ID)
  
      df["accountId"]= list
  </code></pre>
