如何从PDF文件中提取文本? [英] How to extract text from a PDF file?

问题描述

我正在尝试提取使用Python的PDF文件.

I'm trying to extract the text included in this PDF file using Python.

我正在使用 PyPDF2 模块，并具有以下脚本:

I'm using the PyPDF2 module, and have the following script:

import PyPDF2
pdf_file = open('sample.pdf')
read_pdf = PyPDF2.PdfFileReader(pdf_file)
number_of_pages = read_pdf.getNumPages()
page = read_pdf.getPage(0)
page_content = page.extractText()
print page_content

运行代码时，得到以下输出，该输出与PDF文档中包含的输出不同:

When I run the code, I get the following output which is different from that included in the PDF document:

!"#$%#$%&%$&'()*%+,-%./01'*23%4
5'%1$#26%3/%7/))/8%&)/26%8#3"%3"*%313/9#&)
%

推荐答案

正在寻找适用于python 3.x和Windows的简单解决方案.似乎没有来自 textract 的支持，这很不幸，但是如果您正在寻找对于Windows/python 3的简单解决方案，请检出 tika 程序包，对于阅读pdf来说确实很简单.

Was looking for a simple solution to use for python 3.x and windows. There doesn't seem to be support from textract, which is unfortunate, but if you are looking for a simple solution for windows/python 3 checkout the tika package, really straight forward for reading pdfs.

Tika-Python是与Apache Tika™REST服务结合的Python，允许在Python社区中本地调用Tika.

Tika-Python is a Python binding to the Apache Tika™ REST services allowing Tika to be called natively in the Python community.

from tika import parser

raw = parser.from_file('sample.pdf')
print(raw['content'])
