熊猫从“多级”列中选择值
我有一个下面经过测试的小熊猫代码，其中有一个名为Firmware_sheet.xlsx的excl文件，其中有多个详细信息，我看到这些详细信息分为多级列，因此我需要从中提取一些信息。
我只是在学习如何在多级列中工作，我尝试过但暂时无法获得它。.
熊猫代码：
#!/usr/bin/python3
import pandas as pd
pd.set_option('display.width', None)
pd.set_option('expand_frame_repr', True)
firmware = pd.ExcelFile("Firmware_sheet.xlsx")
df = firmware.parse("Sheet1")
print(df)
DataFrame输出：
$ ./Firmware_pandas.py

尽管我已在上面给出了df的详细信息，但只是为了让您理解以下内容。
预期输出：
Applicance Name Composer Firmware Verion Synergy 20Gb BTterconnect LBTk Module Firmware Version Synergy 12Gb SAS Connection Module Firmware Virtual Connect SE 40Gb F8 Module for Synergy Firmware Verion
4.20.02-0395878 1.17 1.17 1.17
谢谢您的帮助。
编辑：（df.columns.tolist（））输出按Jezrael的要求。
[('Applicance Name', 'Unnamed: 0_level_1', 'Unnamed: 0_level_2'), ('Appliance FQDN', 'Unnamed: 1_level_1', 'Unnamed: 1_level_2'), ('Location', 'Unnamed: 2_level_1', 'Unnamed: 2_level_2'), ('Applicance Model', 'Unnamed: 3_level_1', 'Unnamed: 3_level_2'), ('Appliance Details', 'Composer', 'Firmware Verion'), ('BTfra Details', 'Synergy 20Gb BTterconnect LBTk Module', 'Firmware Version'), ('BTfra Details', 'Synergy 20Gb BTterconnect LBTk Module', 'Compatible with Composer ?'), ('BTfra Details', 'Synergy 20Gb BTterconnect LBTk Module', 'Supported Version'), ('BTfra Details', 'Synergy 12Gb SAS Connection Module', 'Firmware Verion'), ('BTfra Details', 'Synergy 12Gb SAS Connection Module', 'Compatible with Composer ?'), ('BTfra Details', 'Synergy 12Gb SAS Connection Module', 'Supported Version'), ('BTfra Details', 'Virtual Connect SE 40Gb F8 Module for Synergy', 'Firmware Verion'), ('BTfra Details', 'Virtual Connect SE 40Gb F8 Module for Synergy', 'Compatible with Composer ?'), ('BTfra Details', 'Virtual Connect SE 40Gb F8 Module for Synergy', 'Supported Version')]
所需列..
[('Applicance Name', 'Unnamed: 0_level_1', 'Unnamed: 0_level_2'),('Appliance Details', 'Composer', 'Firmware Verion'),('BTfra Details', 'Synergy 20Gb BTterconnect LBTk Module', 'Firmware Version'),('BTfra Details', 'Synergy 12Gb SAS Connection Module', 'Firmware Verion'), ('BTfra Details', 'Virtual Connect SE 40Gb F8 Module for Synergy', 'Firmware Verion')]
1 个答案:
答案 0 :(得分：1)
一个想法是将header=[0,1,2]用于MultiIndex：
df = pd.read_excel("Firmware_sheet.xlsx", header=[0,1,2], sheet_name='Sheet1')
然后删除未命名的值并展宽列：
df.columns = [' '.join(y for y in x if 'Unnamed' not in y) for x in df.columns]
最后选择的列名称-第一列和所有带有Firmware Verion文本的列：
df = df.filter(regex='Applicance Name|Firmware Verion')
