python 3.7中的KeyError

Question

The code gives an error saying KeyError in the end. But I believe the code is correct as written by the tutor.

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

def 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 * 0.9
        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() #instance of BarChart class
    chart.add_data(values)
    sheet.add_chart(chart, 'e2')
    wb.save(filename)

filename = 'transactions.xlsx'
work = process_workbook(filename)

检查文件“transactions.xlsx”是否在同一文件夹中。
