Python使用pandas將表格數(shù)據(jù)進行處理_python

作者：IT之一小佬 ? 更新時間： 2022-10-27 編程語言

前言

任務描述：

當前有一份excel表格數(shù)據(jù)，里面存在缺失值，需要對缺失的數(shù)據(jù)到es數(shù)據(jù)庫中進行查找并對其進行把缺失的數(shù)據(jù)進行補全。

excel表格數(shù)據(jù)如下所示：

一、構建es庫中的數(shù)據(jù)

1.1 創(chuàng)建索引

# 創(chuàng)建physical_examination索引
PUT /physical_examination
{
  "settings": {
    "index": {
      "number_of_shards": "1",
      "number_of_replicas": "1"
    }
  },
  "mappings": {
    "properties": {
      "nums": {
        "type": "integer"
      },
      "name": {
        "type": "text"
      },
      "sex": {
        "type": "text"
      },
      "phone": {
        "type": "integer"
      },
      "result": {
        "type": "text"
      }
    }
  }
}

1.2 插入數(shù)據(jù)

【注意：json數(shù)據(jù)不能格式化換行，否則報錯】

# 向physical_examination索引中添加數(shù)據(jù)
POST physical_examination/_bulk
{"index":{"_id":"1"}}
{"nums":1,"name":"劉一","sex":"男","phone":1234567891,"result":"優(yōu)秀"}
{"index":{"_id":"2"}}
{"nums":2,"name":"陳二","sex":"男","phone":1234567892,"result":"優(yōu)秀"}
{"index":{"_id":"3"}}
{"nums":3,"name":"張三","sex":"男","phone":1234567893,"result":"優(yōu)秀"}
{"index":{"_id":"4"}}
{"nums":4,"name":"李四","sex":"男","phone":1234567894,"result":"優(yōu)秀"}
{"index":{"_id":"5"}}
{"nums":5,"name":"王五","sex":"男","phone":1234567895,"result":"優(yōu)秀"}

1.3 查詢數(shù)據(jù)

【注意：默認查詢索引下的所有數(shù)據(jù)】

# 查詢索引中的所有數(shù)據(jù)
GET physical_examination/_search
{
  "query": {
    "match_all": {}
  }
}

二、對excel表格中的數(shù)據(jù)處理操作

2.1 導出es查詢的數(shù)據(jù)

  • 方法一：直接在kibana或postman查詢的結果中進行復制粘貼到一個文檔。
  • 方法二：使用kibana導出數(shù)據(jù)。
  • 方法三：使用postman導出數(shù)據(jù)保存到本地。

使用python處理數(shù)據(jù)，獲取需要的數(shù)據(jù)。

示例代碼：

# 讀取json中體檢信息
with open('./data/physical_examination.json', 'r', encoding='utf-8') as f:
    data_json = f.read()
print(data_json)
 
# 處理json數(shù)據(jù)中的異常數(shù)據(jù)
if 'false' in data_json:
    data_json = data_json.replace('false', "False")
 
data_json = eval(data_json)
print(data_json)
 
print(data_json['hits']['hits'])
print('*' * 100)
 
valid_data = data_json['hits']['hits']
need_data = []
for data in valid_data:
    print(data['_source'])
    need_data.append(data['_source'])
print(need_data)

讀取缺失數(shù)據(jù)的excel表格，把缺失的數(shù)據(jù)填補進去。

# 讀取需要填補數(shù)據(jù)的表格
data_xlsx = pd.read_excel('./data/體檢表.xlsx', sheet_name='Sheet1')
# print(data_xlsx)
 
# 獲取excel表格的行列
row, col = data_xlsx.shape
print(row, col)
 
# 修改表格中的數(shù)據(jù)
for i in range(row):
    bb = data_xlsx.iloc[i]
    print(bb['姓名'], bb['手機號'])
    if pd.isnull(bb['手機號']):
        bb['手機號'] = '666'
        for cc in need_data:
            if cc['name'] == bb['姓名']:
                bb['手機號'] = cc['phone']
            data_xlsx.iloc[i, 3] = bb['手機號']
    print(bb['姓名'], bb['手機號'])
    print("-" * 100)
print(data_xlsx)

將最終處理好的數(shù)據(jù)保存在新建的文件中。

# 保存數(shù)據(jù)到新文件中
data_xlsx.to_excel('./data/new_data.xlsx', sheet_name='Sheet1', index=False, header=True)

完整代碼如下：

import pandas as pd
 
# 讀取json中體檢信息
with open('./data/physical_examination.json', 'r', encoding='utf-8') as f:
    data_json = f.read()
print(data_json)
 
# 處理json數(shù)據(jù)中的異常數(shù)據(jù)
if 'false' in data_json:
    data_json = data_json.replace('false', "False")
 
data_json = eval(data_json)
print(data_json)
 
print(data_json['hits']['hits'])
print('*' * 100)
 
valid_data = data_json['hits']['hits']
need_data = []
for data in valid_data:
    print(data['_source'])
    need_data.append(data['_source'])
print(need_data)
 
# 讀取需要填補數(shù)據(jù)的表格
data_xlsx = pd.read_excel('./data/體檢表.xlsx', sheet_name='Sheet1')
# print(data_xlsx)
 
# 獲取excel表格的行列
row, col = data_xlsx.shape
print(row, col)
 
# 修改表格中的數(shù)據(jù)
for i in range(row):
    bb = data_xlsx.iloc[i]
    print(bb['姓名'], bb['手機號'])
    if pd.isnull(bb['手機號']):
        bb['手機號'] = '666'
        for cc in need_data:
            if cc['name'] == bb['姓名']:
                bb['手機號'] = cc['phone']
            data_xlsx.iloc[i, 3] = bb['手機號']
    print(bb['姓名'], bb['手機號'])
    print("-" * 100)
print(data_xlsx)
 
# 保存數(shù)據(jù)到新文件中
data_xlsx.to_excel('./data/new_data.xlsx', sheet_name='Sheet1', index=False, header=True)

運行效果，最終處理好的數(shù)據(jù)如下所示：
