如何使用熊貓/ python處理excel文件標題

Question

我想使用熊貓閱讀https://www.whatdotheyknow.com/request/193811/response/480664/attach/3/GCSE%20IGCSE%20results%20v3.xlsx。

救了它在我的劇本是

import sys 
import pandas as pd 
inputfile = sys.argv[1] 
xl = pd.ExcelFile(inputfile) 
# print xl.sheet_names 
df = xl.parse(xl.sheet_names[0]) 
print df.head() 

然而，這似乎並沒有正確處理標題，因爲它給

GCSE and IGCSE1 results2,3 in selected subjects4 of pupils at the end of key stage 4 Unnamed: 1 Unnamed: 2 Unnamed: 3 Unnamed: 4 Unnamed: 5 Unnamed: 6 Unnamed: 7 Unnamed: 8 Unnamed: 9 Unnamed: 10

4 2. Includes attempts and achievements by these...           NaN  NaN  NaN  NaN  NaN  NaN  NaN  NaN  NaN   NaN 

所有這一切都應該被視爲註釋。

例如，如果您將電子表格加載到libreoffice中，則可以看到列標題被正確解析並出現在第15行的下拉菜單中，以便您選擇所需的項目。

如何讓熊貓自動檢測列標題的位置與libreoffice一樣？

Answer 1

pandas是（are？）正確處理文件，並且完全按照你問它（他們？）的方式來處理。您沒有指定header值，這意味着它默認從第0行獲取列名稱。細胞的前幾行是不以某種根本的辦法的意見，他們只是沒有電池你有興趣

只需告訴parse你想跳過一些行：

>>> xl = pd.ExcelFile("GCSE IGCSE results v3.xlsx") 
>>> df = xl.parse(xl.sheet_names[0], skiprows=14) 
>>> df.columns 
Index([u'Local Authority Number', u'Local Authority Name', u'Local Authority Establishment Number', u'Unique Reference Number', u'School Name', u'Town', u'Number of pupils at the end of key stage 4', u'Number of pupils attempting a GCSE or an IGCSE', u'Number of students achieving 8 or more GCSE or IGCSE passes at A*-G', u'Number of students achieving 8 or more GCSE or IGCSE passes at A*-A', u'Number of students achieving 5 A*-A grades or more at GCSE or IGCSE'], dtype='object')
