我是Python的新手，所以也许有一种我不知道的简单方法。
但基本上，我有一个由API返回的dict的JSON数组：

我正在检索这些项目并提示用户输入ID。此ID必须与列表中的jobid之一匹配。如果没有，我只是想退出。我不确定获取用户输入的内容并验证其实际存在于数组中的最佳方法。
答案 0 :(得分：3)
您可以列出Jobid并检查其中是否包含输入内容：
jobids = [job["jobid"] for job in your_json]
if input_id not in jobids:
raise ValueError(f"Bad jobid: {input_id}")
# The rest of your code that relies on input_id being in the json goes here...
答案 1 :(得分：1)
这就是我要做的方式：
def search_in_json(json_list, id):
filtered_json = list(filter(lambda x: x['jobid'] == id, json_list))
if filtered_json:
return filtered_json # Or whatever you want to return
else:
return 0 # Or raise an error
答案 2 :(得分：1)
您可以使用此功能检查ID是否存在：
as.Date()
