#Below code will work even if you don't know the exact sheet_names in the excel file. You can try this:

import pandas as pd

xls = pd.ExcelFile('myexcel.xls')

out_df = pd.DataFrame()

for sheet in xls.sheet_names:
    df = pd.read_excel('myexcel.xls', sheet_name=sheet)
    out_df.append(df)  ## This will append rows of one dataframe to another(just like your expected output)

print(out_df)

## out_df will have data from all the sheets
