我正在学习弹性搜索,并希望计算不同的值.到目前为止,我可以计算值,但不是很明显.

以下是示例数据:

curl http://localhost:9200/store/item/ -XPOST -d '{
  "RestaurantId": 2,
  "RestaurantName": "Restaurant Brian",
  "DateTime": "2013-08-16T15:13:47.4833748+01:00"
}'

curl http://localhost:9200/store/item/ -XPOST -d '{
  "RestaurantId": 1,
  "RestaurantName": "Restaurant Cecil",
  "DateTime": "2013-08-16T15:13:47.4833748+01:00"
}'

curl http://localhost:9200/store/item/ -XPOST -d '{
  "RestaurantId": 1,
  "RestaurantName": "Restaurant Cecil",
  "DateTime": "2013-08-16T15:13:47.4833748+01:00"
}'

到目前为止我尝试了什么:

curl -XPOST "http://localhost:9200/store/item/_search" -d '{
  "size": 0,
  "aggs": {
    "item": {
      "terms": {
        "field": "RestaurantName"
      }
    }
  }
}'

输出:

{
  "took": 0,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
  "hits": {
    "total": 3, …

我写了一个程序,我添加了两列并将答案写入CSV文件,但是当我只想编写列的选择时,我收到错误.这是我的逻辑:

import pandas as pd

df = pd.DataFrame({'A' : ['foo', 'bar', 'foo', 'bar',
                           'foo', 'bar', 'foo', 'bar'],
                'B' : ['one', 'one', 'two', 'two',
                          'two', 'two', 'one', 'two'],
                'C' : [56, 2, 3, 4, 5, 6, 0, 2],
                'D' : [51, 2, 3, 4, 5, 6, 0, 2]})

grouped = df.groupby(['A', 'B']).sum()

grouped['sum'] = (grouped['C'] / grouped['D']) 
# print (grouped[['sum']])


a = pd.DataFrame(grouped)


a.to_csv("C:\\Users\\test\\Desktop\\test.csv", index=False, cols=('A','B','sum'))

我怎么才能写出A,B和Sum列的数据.我收到以下错误

Traceback (most recent call last):
  File "C:\Users\test\Desktop\eclipse\yuy\group.py", line 19, in <module>
    a.to_csv("C:\\Users\\test\\Desktop\\test.csv", index=False, cols=('A','B','sum')) …

我会说我不是VBA的专家.我有一个VBA代码,它在一个单元格中附加选定列表中的多个值.代码有效,但现在我想将代码应用于多个单元格.

嗨,我是bash编程的新手,我正在读代码,但我无法理解一件事.-gt在这段代码中意味着什么

if [ $result -gt 0 ] ; 
    then  
       exit 1 ;
