Python 循环代码与 try: & except: pass答案

【问题描述】：

在抓取 json 文件列表时，有时文件丢失，无法下载。在我的 python 脚本中，当这种情况发生时，脚本会显示错误

json.decoder.JSONDecodeError：期望值：linke 1 column 1 (char 0)

如果出现错误，我如何要求脚本继续循环？我试了试：except，但没有成功（IndentationError）

这是代码：

RACE_L = x1["pageProps"]["initialState"]["racecards"]["races"][today2]
for r1 in RACE_L:
    id_race = r1["uuid"]
    link2go = link_append + id_race + '.json'
    n1 = "races"
    n12 = "races"
    n2 = r1["uuid"]
    name1 = n12 + '-' + n2
    name1 = today2 + '_' + name1 + '.json'
    with open(path +'%s' %name1,'w',encoding='utf-8') as f2:
        print('Writing %s into file' %name1)
        r3 = requests.get(link2go, headers=headers)
        sleep(2)
        x3 = r3.json()
        json.dump(x3, f2, indent=4, ensure_ascii=False)

【问题讨论】：

您尝试放置 try 和 except 块的代码在哪里？
就在 RACE_L 中的 r1 下方：

【解决方案1】：

以这种方式放置 try 和 except 块-

RACE_L = x1["pageProps"]["initialState"]["racecards"]["races"][today2]
for r1 in RACE_L:
    try:
        id_race = r1["uuid"]
        link2go = link_append + id_race + '.json'
        n1 = "races"
        n12 = "races"
        n2 = r1["uuid"]
        name1 = n12 + '-' + n2
        name1 = today2 + '_' + name1 + '.json'
        with open(path +'%s' %name1,'w',encoding='utf-8') as f2:
            print('Writing %s into file' %name1)
            r3 = requests.get(link2go, headers=headers)
            sleep(2)
            x3 = r3.json()
            json.dump(x3, f2, indent=4, ensure_ascii=False)
    except:
        pass
