import xlsxwriter
workbook=xlsxwriter.workbook(r'C:\Users\admin\Desktop\6_6.xlsx')
work_sheet=workbook.add_worksheet('demo')
format_dict={
"bold":True,
"font_color":'#DC143c',
'font_size':20
}
text_format=workbook.add_format(format_dict)
header=['门票总额','购物费用总额','旅途费用总额','年消费总额']
data=[742.6,4399,1298]
data.append(sum(data))
print(data)
workbook.close()

Traceback (most recent call last):
