使用熊猫从不同的Excel工作表中的行中获取特定的字符串

Question

I have an excel file with different sheets, each sheet containing cities names with some data. For example:

Istanbul  Paris Barcelona
1          2        3
4          2        6

In every sheet, I want to extract the row for each cell where Paris = 2. So far, I have :

import pandas
xls= pandas.ExcelFile('cities.xlsx')
sheets= xls.sheet_names
print sheets
#Dialogue Result
for row in sheets.iter_rows():
   row = sheet.row("Paris")
   print row.index()

Answer 1

You can using pd.concat

import pandas as pd
xls = pd.ExcelFile('path_to_file.xls')
alldf=pd.concat([xls.parse(x) for x in xls.sheet_names],keys=xls.sheet_names)

alldf.loc[alldf.Paris==2,:]
