尝试和Python请求除外

标签: python try-except

如果下面的脚本已经运行,它会从我想要的所有人开始(例如:Nick Ahmed,Alex Avila等)。但是在9个左右之后给我一个KeyError: 'row'

SCRIPT

import csv
import requests
import datetime
from pprint import pprint

# GET TEAM ID AND STORE AS team_id
req = requests.get('http://lookup-service-prod.mlb.com/json/named.team_all_season.bam?sport_code=%27mlb%27&all_star_sw=%27N%27&sort_order=name_asc&season=%272018%27') 
data = req.json()['team_all_season']['queryResults']['row']

for teams in data:
    team_id = teams['team_id']
    team = teams['name_abbrev']

    # GET PLAYER ID using team_id string and store PLAYER ID as playerId
    req1 = requests.get('http://lookup-service-prod.mlb.com/json/named.roster_40.bam?team_id=' + str(team_id) + '') 
    roster = req1.json()['roster_40']['queryResults']['row']

    for info in roster:
        player = info['name_display_first_last']
        playerId = info['player_id']

        # Use playerId string to run through PECOTA BATTING PROJECTIONS
        req2 = requests.get("http://lookup-service-prod.mlb.com/json/named.proj_pecota_batting.bam?season='2018'&player_id='" + str(playerId) + "'") 
        info1 = req2.json()['proj_pecota_batting']['queryResults']['row']
        # KEYS 
        hr = info1['hr']
        sac = info1['sac']
        rbi = info1['rbi']
        tb = info1['tb']
        slg = info1['slg']
        bavg = info1['avg']
        bb = info1['bb']
        ops = info1['ops']
        hbp = info1['hbp']
        games = info1['g']
        d = info1['d']
        e = info1['e']
        so = info1['so']
        sf = info1['sf']
        tpa = info1['tpa']
        h = info1['h']
        cs = info1['cs']
        obp = info1['obp']
        t = info1['t']
        s = info1['s']
        r = info1['r']
        sb = info1['sb']
        sbpct = info1['sbpct']
        ab = info1['ab']
        ibb = info1['ibb']

        print(player,team,hr,sac,rbi,tb,slg,bavg,bb,ops,hbp,games,d,e,so,sf,tpa,h,cs,obp,t,s,r,sb,sbpct,ab,ibb)

如果我添加try: except(KeyError):它会起作用,但会在此过程中跳过很多玩家,就像我之前使用的示例一样。这对我没有意义,因为如果他们在try之前工作,他们为什么不现在呢?仅复制以下脚本的已编辑部分,以显示try: except:

脚本编辑:

try:
    info1 = req2.json()['proj_pecota_batting']['queryResults']['row']
except(KeyError):

答案 0 :(得分:1)

以下是try except应该如何:

import csv
import requests
import datetime
from pprint import pprint

##outfile = open('MLB_HITTER_PICOTA_' + datetime.datetime.now().strftime('%Y') + '.csv','w',newline='')
##writer = csv.writer(outfile)
##writer.writerow(["mlb_hitter","team","hr","sac","rbi","tb","slg","bavg","bb","ops","hbp","games","d","e","so","sf","tpa","h","cs","obp","t","s","r","sb","sbpct","ab","ibb"])

data = req.json()['team_all_season']['queryResults']['row']

for teams in data:
    team_id = teams['team_id']
    team = teams['name_abbrev']

    # GET PLAYER ID using team_id string and store PLAYER ID as playerId
    req1 = requests.get('http://lookup-service-prod.mlb.com/json/named.roster_40.bam?team_id=' + str(team_id) + '') 
    roster = req1.json()['roster_40']['queryResults']['row']

    for info in roster:
        player = info['name_display_first_last']
        playerId = info['player_id']

        req2 = requests.get("http://lookup-service-prod.mlb.com/json/named.proj_pecota_batting.bam?season='2018'&player_id='" + str(playerId) + "'")
##        pprint(req2.text)
        try:

        except(KeyError):
            pass
