python 实现读取一个excel多个sheet表并合并的方法

如下所示：

importxlrd

importpandas as pd

frompandas importDataFrame

DATA_DIR ='E:/'

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()

fori inrange(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))
