python 实现读取一个excel多个sheet表并合并的方法

如下所示：

import xlrd

import pandas as pd

from pandas import DataFrame

  

DATA_DIR = 'D:/'

 

excel_name = '%s2017.xls' % DATA_DIR

wb = xlrd.open_workbook(excel_name)

# print(wb)

  

# 获取workbook中所有的表格

sheets = wb.sheet_names()

# print(sheets)

  

# 循环遍历所有sheet

df_28 = DataFrame()

for i in range ( len (sheets)):

 

# skiprows=2 忽略前两行

df = pd.read_excel(excel_name, sheet_name = i, skiprows = 2 , index = False , encoding = 'utf8' )

df_28 = df_28.append(df)

 

# 去除缺省值

df_28 = df_28.dropna()

df_28 = df_28.reset_index(drop = True )

print ( len (df_28))
