Question

我遵循了一个指南，该指南创建了一个非常基本的脚本以通过pycharm进行编辑和xlsx，并创建了图表，但出现了一个错误，该错误使我无法保存文件。

我是一个绝对的初学者，所以不确定我的代码中的错误在哪里。

    import openpyxl as xl
from openpyxl.chart import BarChart, Reference

wb = xl.load_workbook('transactions.xlsx')
sheet = wb['Sheet1'] 
cell = sheet['a1']

for row in range(2,sheet.max_row + 1):
    cell = sheet.cell(row,3) 
    corrected_price = cell.value *0.9
    corrected_price_cell = sheet.cell(row,4)
    corrected_price_cell.value = corrected_price

values = Reference(sheet,
          min_row=2,
          max_row=sheet.max_row,
          min_col=4,
          max_col=4
          )

chart = BarChart()
chart.add_data(values)
sheet.add_chart(chart, 'e2')

wb.save('transactions2.xlsx')

我希望在第4列中获得一个带有一些新值的新xlsx文件，然后在单元格e2处获得一个基本的条形图，其中包含第4列中的值。

我得到的是崩溃-它创建了文件，但无法打开，并且pycharm中出现许多错误。
