如何用python合并多个excel文件

pip3 install xlrd
pip3 install XlsxWriter

import xlsxwriter

# 创建一个工作簿并添加一个工作表
workbook = xlsxwriter.Workbook("c.xlsx")
worksheet = workbook.add_worksheet()

# 设置列宽
worksheet.set_column("A:A", 20)

# 设置格式
bold = workbook.add_fORMat({"bold": True})

# 设置单元格的值
worksheet.write("A1", "Hello")

# 带格式的单元格
worksheet.write("A2", "World")

# 写一些数字，用行列标识
worksheet.write(2, 0, 123)
worksheet.write(3, 0, 123.456, bold)

# 插入一张图片
worksheet.insert_image("B5", "s.png")

# 关闭文件流
workbook.close()
