python 实现读取一个excel多个sheet表并合并的方法

Posted 2021-03-04 幻雪追梦

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))
