Python .xslx文件赢得'；使用openpyxl返回单元格值

我对编码非常陌生，我从Python开始。我正在尝试使用openpyxl作为教程的一部分。具体来说，我正在尝试打印Excel工作簿中工作表中特定单元格的值。我跟随教程，将文件添加到我的项目中，并拥有与教学视频中相同的代码，但我很难理解错误。起初Pycharm无法识别目录，因此我修复了该问题，但它仍然返回几个错误。希望有人能启发一个迷失的新手！我非常感激

代码如下：

import openpyxl as xl

wb = xl.load_workbook("transactions.xlsx")

sheet = wb["Sheet1"]

**#instead of the method below, I have also tried: cell = sheet["a1"] to specify the cell I want.**

cell = sheet.cell(1, 1)

print(cell.value)

这里是错误：

import openpyxl as xl

wb = xl.load_workbook("transactions.xlsx")

sheet = wb["Sheet1"]

**#instead of the method below, I have also tried: cell = sheet["a1"] to specify the cell I want.**

您可以指定

transactions.xlsx

的完整路径，例如

/home/user/filename.ext

，或者将

transactions.xlsx

文件放在与python文件相同的目录中，或者我可以说是run path。它可能是

C:\Users\acost\AppData\Roaming\JetBrains\PyCharmCE2021.1\scratch
