文件解析：doc、docx、pdf

1.doc解析

ubuntu/debian系统应先安装工具

apt-get install python-dev libxml2-dev libxslt1-dev antiword unrtf poppler-utils pstotext tesseract-ocr \
flac ffmpeg lame libmad0 libsox-fmt-mp3 sox libjpeg-dev swig
pip install textract

解析：

import textract
text = textract.process(doc_file, input_encoding='utf-8')
text_str = str(text, 'utf-8')
print(text_str)

2.docx解析

pip install python-docx

from docx import Document
import docx2txt

def read_docx(docx_file):
    doc = Document(docx_file)
    text = []
    for paragraph in doc.paragraphs:
        text.append(paragraph.text)
    return '\n'.join(text)
read_docx('path.docx')
