python - Run a block of code each time a condition is met -

first off, sorry wall of text. try explain issue as can.

hello, title may think refer simple if statement , may true. i've done questions today project , want else. i'm doing bot using league of legends api. bot print stats current game of given player. unfamiliar game, there ranks. rank 1 of stats bot prints chat working on; stats ranked games, unlike normal games, ranked games ones count these stats. anyway; i'm getting data json , each time player unranked (not ranked player) 404 request , want handle 404 print else. right now, important part of code:

            ids_seen = set()             y in range(0, 10):                 num += 1                 = r_match['participants'][num]                 e_name = i['summonername']                 e_id = i['summonerid']                 team_id = i['teamid']                 champ = i['championid']                  r_team = requests.get("https://lan.api.pvp.net/api/lol/lan/v2.5/league/by-summoner/{}/"                                       "entry?api_key=".format(e_id)).json()                  champ_r = requests.get("https://global.api.pvp.net/api/lol/static-data/lan/v1.2/champion?"                                        "api_key=").json()                  x = r_team["{}".format(e_id)][0]                 e_tier = x['tier']                 e_div = x['entries'][0]['division']                  key, value in champ_r['data'].items():                     c_name = value['name']                     c_id = value['id']                      chat_say = """ {} - {} {} - playing `#{}`""".format(e_name, e_tier, e_div, c_name)                      if champ == c_id: #                         if r_team['status']['status_code'] == 404: #                             unranked_term = (e_name + " - " + "unranked") #                             unranked_say = """ # {} - playing `#{}`""".format(unranked_term, c_name) #                             yield bot.send_message(message.channel, unranked_say)                          # else:                             if team_id == 100:                                 if not team_id in ids_seen:                                     yield bot.send_message(message.channel, "```---blue team---```")                                 yield bot.send_message(message.channel, chat_say)                              elif team_id == 200: #                                 if r_team['status']['status_code'] == 404: #                                     unranked_term = (e_name + " - " + "unranked") #                                     unranked_say = """ # {} - playing `#{}`""".format(unranked_term, c_name) #                                     yield bot.send_message(message.channel, unranked_say)                                  if not team_id in ids_seen:                                     yield bot.send_message(message.channel, "```--- red team ---```")                                 yield bot.send_message(message.channel, chat_say)                  ids_seen.add(team_id)                  yield asyncio.sleep(1) 

when run code output this:

player1 - rank - champion being played player2 - rank - champion being played player3 - rank - champion being played... 

... , on; while happening if finds unranked player mentioned before throws keyerror because, well, can't find ranked data on json. so; commented out lines ones want implement.

this:

#                         if r_team['status']['status_code'] == 404: #                             unranked_term = (e_name + " - " + "unranked") #                             unranked_say = """ # {} - playing `#{}`""".format(unranked_term, c_name) #                             yield bot.send_message(message.channel, unranked_say) 

i tried placing , getting keyerror again; if place right here:

                    if team_id == 100:                             # <- right here if i'm not wrong.                         if not team_id in ids_seen:                             yield bot.send_message(message.channel, "```---blue team---```")                         yield bot.send_message(message.channel, chat_say) 

i players , champions being played ranks of each 1 displayed unranked; unranked. question is, how can implement code? i'm not sure if i'm in right path on doing this.

i output like:

player1 - rank - champion # if has ranked information player2 - rank - champion # same player3 - unranked - champion # if player unranked 

everything can run bot because every time there unranked error , can't avoid (except looking match without unranked player)

thanks help! :)

you can try adding try except block @ exact place getting keyerror, try value @ key, if not exist, catch exception not exist , can handle exception wish (in case, unranked player)

for example - if json or dict

jsonobj = {    "players":[       {          "rank":"500",          "name":"iamranked"       },       {          "name":"iamnotranked"       }    ] } 

then, if surround try except block this:

# examples try:     print(jsonobj['players'][0]['rank']) #surround assignement try catch block     print("i have rank") # print rank exists except keyerror:     print("i not have rank")  try:     print(jsonobj['players'][1]['rank'])     print("i have rank") except keyerror:     print("i not have rank") # print rank not exist 

hope helps!
