问题描述
我使用以下代码：
import json
full_json = "{'Nike - Hombres Tenis Fila': ['/nike/casual/','100','/medias/']}"
jtopy=json.dumps(full_json) #json.dumps take a dictionary as input and returns a string as output.
dict_json=json.loads(jtopy)
print(dict_json['Nike - Hombres Tenis Fila'][0])
我如何获得价值： /nike/casual/runners/'
我不断收到错误消息：
解决方法
您的 json 无效，您需要交换单引号和双引号。
您还需要 <div class="panel-heading">
<h1 style="text-align: center">Students</h1><br>
<div class="form-group">
<input type="text" class="form-control search-input" placeholder="Search..." [(ngModel)]="filterTerm">
</div>
<div class="panel-body">
<table class="table table-hover table-sm">
<thead class="thead-light">
<tr>
<th>Student code</th>
<th>Student name</th>
<th>Student date</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<tr *ngFor="let student of students| filter:filterTerm">
<td>{{student.codestudent}}</td>
<td>{{student.namestudent}}</td>
<td>{{student.datestudent}}</td>
<td><button (click)="deleteStudent(student.codestudent)" class='btn btn-primary'><i
class="fa fa-futboll-0">Delete</i></button>
</td>
</tr>
</tbody><br>
</table>
</div> 而不是 json.loads
json.dumpsJson 在其字符串中不接受单引号。要进行查询，您应该：
- 将您的 json 字符串替换为此
'{"Nike - Hombres Tenis Fila": ["/nike/casual/","100","/medias/"]}' - 运行 json.loads
dictjson = json.loads('{"Nike - Hombres Tenis Fila": ["/nike/casual/","/medias/"]}') - 做你的查询
dictjson["Nike - Hombres Tenis Fila"][0]
