Question

我编写了一个python脚本，该脚本从pdf文档中抓取帐号，并且在本地运行良好。我已经使用pyinstaller将脚本提取到可执行文件中，并将其保存到闪存驱动器中。我将pdf文档移到了我认为是CWD的位置，但是当我尝试运行它时，终端告诉我我要打开的pdf文件找不到。

最终，我希望我的客户端能够放入闪存驱动器，将pdf的最新版本移至同一目录，然后运行脚本。我需要在正确的方向上微调如何为PyPDF2指定文件路径。到目前为止，这是我的代码。

def getDataFromPdf():
acctNumberRegex = re.compile(r'\d\d\d\d\d-\d\d\d-\d\d\d\d')
pdfFile = open('records.pdf', 'rb')
reader = PyPDF2.PdfFileReader(pdfFile)
for pageNum in range(0,10):
    page = reader.getPage(pageNum).extractText()
    accounts = acctNumberRegex.findall(page)
    for acct in accounts:
        if acct not in results:
            results.append(acct)
print(len(results))

谢谢！

Answer 1

您可以将文件路径作为参数传递给函数。

所以：

def getDataFromPdf(filePath):
    acctNumberRegex = re.compile(r'\d\d\d\d\d-\d\d\d-\d\d\d\d')
    pdfFile = open(filePath + 'records.pdf', 'rb')
    reader = PyPDF2.PdfFileReader(pdfFile)
    for pageNum in range(0,10):
        page = reader.getPage(pageNum).extractText()
        accounts = acctNumberRegex.findall(page)
    for acct in accounts:
        if acct not in results:
          results.append(acct)
    print(len(results))
