[{'name': 'Alice', 'age': 25, 'gender': 'female'}, {'name': 'Cindy', 'age': 25, 'gender': 'female'}] 移除第一个字典

可以使用Python中的列表切片来移除第一个字典,示例代码如下:
```
lst = [{'name': 'Alice', 'age': 25, 'gender': 'female'}, {'name': 'Cindy', 'age': 25, 'gender': 'female'}]
lst = lst[1:]
print(lst)
```
输出:
```
[{'name': 'Cindy', 'age': 25, 'gender': 'female'}]
```

{"name":"Michael", "age": 25, "gender": "male"} {"name":"Andy", "age":30, "gender":"female"} {"name":"Justin", "age":19, "gender": "female"}使用Spark 读取female的人
您可以使用Spark SQL来读取这些数据,并筛选出gender为"female"的人。以下是示例代码:
```python
from pyspark.sql import SparkSession
# 创建SparkSession
spark = SparkSession.builder.appName("read_data").getOrCreate()
# 读取数据
data = spark.read.json("path/to/json/file")
# 筛选出gender为"female"的人
female_data = data.filter(data.gender == "female")
# 展示筛选结果
female_data.show()
```
其中,"path/to/json/file"应该替换为您实际的JSON文件路径。`show()`方法可以展示筛选结果,默认展示前20行。
将下述{ "class": "1A", "teacher": "Mr. Smith", "students": [ { "name": "Alice", "age": 12, "gender": "female" }, { "name": "Bob", "age": 13, "gender": "male" } ] }json串中的students数组转换成对象并打印对象
好的,您可以使用以下JavaScript代码将JSON字符串解析为JavaScript对象,然后打印出students数组对应的对象:
```javascript
const jsonString = '{ "class": "1A", "teacher": "Mr. Smith", "students": [ { "name": "Alice", "age": 12, "gender": "female" }, { "name": "Bob", "age": 13, "gender": "male" } ] }';
const jsonObject = JSON.parse(jsonString);
const studentsObject = jsonObject.students;
console.log(studentsObject);
```
运行结果如下:
```
[
{ name: 'Alice', age: 12, gender: 'female' },
{ name: 'Bob', age: 13, gender: 'male' }
]
```
其中,studentsObject就是JSON中students数组对应的JavaScript对象。
