注意：

注意xlsx的格式，wps一定另存为xlsx才可以，不然就出错。

操作表格

1，在终端里面安装openpyxl

        pip install openpyxl

import openpyxl as xl
from openpyxl.chart import BarChart,Reference#注意xlsx的格式，wps另存为xlsx才可以，奇怪
wb = xl.load_workbook('transaction1.xlsx')sheet = wb['Sheet1']
cell = sheet['A1']
cell = sheet.cell(1,1)print(cell.value)
print(sheet.max_row)for row in range(2, sheet.max_row+1):cell = sheet.cell(row,3)corrected_price = cell.value *0.9corrected_price_cell = sheet.cell(row,4)corrected_price_cell.value = corrected_price

输出柱状图

#输出柱状图 chart_values = Reference(sheet, min_row=2, max_row=sheet.max_row, min_col=4, max_col=4) chart = BarChart() chart.add_data(chart_values) sheet.add_chart(chart,'E2')

自动化处理：

#改为函数，可以做自动化处理，只要传入文件名即可。import openpyxl as xl
from openpyxl.chart import BarChart,Referencedef process_workbook(filename):wb = xl.load_workbook(filename)sheet = wb['Sheet1']for row in range(2, sheet.max_row+1):cell = sheet.cell(row,3)corrected_price = cell.value *0.9corrected_price_cell = sheet.cell(row,4)corrected_price_cell.value = corrected_pricechart_values = Reference(sheet,min_row=2,max_row=sheet.max_row,min_col=4,max_col=4)chart = BarChart()chart.add_data(chart_values)sheet.add_chart(chart,'E2')wb.save(filename)
