pyPDF2中的extractText（）函数抛出错误

Question

我正在尝试从PDF中提取文本，以便可以对其进行分析，但是当我尝试从页面中提取文本时，出现以下错误。

Traceback (most recent call last):

File "C:\Program Files (x86)\eclipse\plugins\org.python.pydev_2.7.4.2013051601\pysrc\pydevd_comm.py", line 765, in doIt

    result = pydevd_vars.evaluateExpression(self.thread_id, self.frame_id, self.expression, self.doExec)

    data = [y for y in data if not (y in ' \n\r\t')]

File "C:\Python33\lib\site-packages\pypdf2-1.9.0-py3.3.egg\PyPDF2\filters.py", line 170, in <listcomp>

    data = [y for y in data if not (y in ' \n\r\t')]

TypeError: 'in <string>' requires string as left operand, not int

相关代码节如下：

from PyPDF2 import PdfFileReader

for PDF_Entry in self.PDF_List:

    Pdf_File = PdfFileReader(open(PDF_Entry, "rb"))

    for pg_idx in range(0, Pdf_File.getNumPages()):

        page_Content = Pdf_File.getPage(pg_idx).extractText()

        for line in page_Content.split("\n"):

            self.Analyse_Line(line)

将错误抛出在extractText（）行。

Answer 1

您正在一行中做两件事。尝试打破所做的事情以进一步解决问题。改变：page_Content = Pdf_File.getPage(pg_idx).extractText()进入page = Pdf_File.getPage(pg_idx)page_Content = page.extractText()查看错误发生的位置。还要从命令行而不是从Eclipse运行该程序，只是为了确保它是相同的错误。您说它发生在，extractText()但是该行没有显示在回溯中。
