Python Pandas将多个dataframe写入Excel文件

import pandas as pd

if __name__ == '__main__':
	result_file = "monitor_data.xlsx"
	pre_month_data = pd.read_csv(f"./pre_month_data", delimiter="\t")
	pre_week_data = pd.read_csv(f"./pre_week_data", delimiter="\t")
	all_data = pd.read_csv(f"./all_data", delimiter="\t")

	pre_data = pd.concat([pre_month_data, pre_week_data], axis=0)

	all_data.to_excel(result_file, index=False, sheet_name="all_data")
	excel_writer = pd.ExcelWriter(result_file, mode='a', engine="openpyxl")
	pre_data.to_excel(excel_writer, index=False, sheet_name="pre_data")

	excel_writer.save()
	excel_writer.close()
