问题陈述

我使用pdfminer，它是一个工具，可以与Python3一起使用，用于从PDF文档中提取信息。问题是根本没有好的文档，也没有关于如何使用该工具的源代码示例。

我已经尝试过来自StackOverflow的一些代码，但是没有成功。下面是我的密码。

代码段

from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
from pdfminer.pdfinterp import PDFResourceManager
from pdfminer.pdfinterp import PDFPageInterpreter
from pdfminer.converter import TextConverter

def foo(path, password, bankname):
    rsrcmgr = PDFResourceManager()
    retstr = io.StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, laparams=laparams)
    fp = open(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    maxpages = 2
    caching = True
    pagenos = set()
    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages, password=password, caching=caching,
                                  check_extractable=False):  # This is Line 49
        interpreter.process_page(page)
    text = retstr.getvalue()

试着在说明前插入密码= "“。
