FileNotFoundError 当 load_workbook 使用传递过来的文件名

Question

我定义了一个函数并从 for 循环传递了它的参数，得到了 FileNotFoundError: [Errno 2] No such file or directory: 'revenue.xlsx'.

for 循环有效，函数在单独打印时也有效。所以我假设在传递参数时出了点问题。

这是我的全部代码。

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


def process_workbook(file_name):
    wb = xl.load_workbook(file_name)
    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
    data = Reference(sheet, min_col=4, min_row=2, max_row=sheet.max_row)
    cats = Reference(sheet, min_col=1, min_row=2, max_row=sheet.max_row)

    chart = BarChart()
    chart.add_data(data)
    chart.set_categories(cats)
    sheet.add_chart(chart, 'F2')

    wb.save(file_name)
    return file_name


path = Path('/Users/yugao/Downloads/Python Tutorial Supplementary Materials')
for file in path.glob('*.xlsx'):
    filename = file.name
    process_workbook(filename)

这是我的错误：

  File "/Users/yugao/PycharmProjects/HelloWorld/app.py", line 33, in <module>
    process_workbook(filename)
  File "/Users/yugao/PycharmProjects/HelloWorld/app.py", line 7, in process_workbook
    wb = xl.load_workbook(filen_ame)

    self.archive = _validate_archive(fn)

    self.fp = io.open(file, filemode)
FileNotFoundError: [Errno 2] No such file or directory: 'revenue.xlsx'

Answer 1

您还需要提供文件的路径（我认为）。

filename=str(path)+'/'+filename

Answer 2

# Define path to excel file
path = os.path.dirname(os.path.abspath(__file__))

# Define filename
filename=str(path)+'/'+filename

上面的代码片段修复了我遇到的 Exception has occurred: com_error 问题。非常感谢 Kilian！
