Это должно делать то, что вы хотите.
import pandas as pd
import numpy as np
import glob
glob.glob("C:/your_path_here/*.xlsx")
all_data = pd.DataFrame()
for f in glob.glob("C:/your_path_here/*.xlsx"):
df = pd.read_excel(f)
all_data = all_data.append(df,ignore_index=True)
print(all_data)
Вот еще один вариант для рассмотрения.
import pandas as pd
# filenames
excel_names = ["C:/your_path_here/Book1.xlsx", "C:/your_path_here/Book2.xlsx", "C:/your_path_here/Book3.xlsx"]
# read them in
excels = [pd.ExcelFile(name) for name in excel_names]
# turn them into dataframes
frames = [x.parse(x.sheet_names[0], header=None,index_col=None) for x in excels]
# delete the first row for all frames except the first
# i.e. remove the header row -- assumes it's the first
frames[1:] = [df[1:] for df in frames[1:]]
# concatenate them..
combined = pd.concat(frames)
# write it out
combined.to_excel("c.xlsx", header=False, index=False)
# Results go to the default directory if not assigned somewhere else.
