我正在打开 ndjson 文件并尝试遍历字典以选择所有患者的id, birthDate和deceasedDateTime

读取 ndjson 文件的 Python 代码

import ndjson 

 with open('Patients.ndjson') as f:
   data = ndjson.load(f)
  return render_template('home.html', patient =  data)

Html 模板 这个 for 循环显示 html 页面中的所有项目和值。

我如何只从给定的字典中选择特定的值id？ birthDatedeceasedDateTime

{% for i in patient : %}
{% for item, value in i.items(): %}
     <tr>
       <td>{{ item }}</td>
         <td>{{ value }}</td>
      </tr>
     {% endfor %}
{% endfor %}

请参阅关于 jinja2 的变量部分，您只需稍作改动：

主文件

from flask import Flask, render_template
import ndjson 


app = Flask(__name__)


template = "tmp.html"


@app.route('/')
def main():
    with open('patients.ndjson') as f:
        patients = ndjson.load(f)

    return render_template(template, patients=patients)



if __name__ == '__main__':
    app.run(debug=True)```

tmp.html

{% for patient in patients %}
    <tr>
        <td>{{ patient.id }}</td>
        <td>{{ patient.birthDate }}</td>
        <td>{{ patient.deceasedDateTime }}</td>
    </tr></br>
{% endfor %}

编辑

作为一个仅供参考，当在 python 中加载一个 ndjson 时，它会变成一个字典列表。在您的模板中，您需要遍历列表，并使用我的示例中所示的键为每个 dict 项目获取正确的值。

你可以使用dict.items()，但这会给你所有无序的键/值对......

fe，使用以下将打印出 NDJSON 中每一行的整个 JSON：

{% for patient in patients %}
    {% for key,val in patient.items()  %}
        {{ key }}: {{val}}</br>
    {% endfor %}
{% endfor %}
