无法使我的脚本以所需格式打印输出

Question

I'm trying to extract a certain portion of text from a pdf file. I've used PyPDF2 library to do that. However, when i excecute the script below I can see that the content I wish to grab is being printed in the console awkwardly.

I've written so far:

import io
import PyPDF2
import requests

URL = 'http://www.ct.gov/hix/lib/hix/CT_DSG_-12132014_version_1.2_%28with_clarifications%29.pdf'

res = requests.get(URL)
f = io.BytesIO(res.content)
reader = PyPDF2.PdfFileReader(f)
contents = reader.getPage(0).extractText()
print(contents)

Output I'm having:

ACCESSHEALTHCTConnecticutAllPayersClaimsDatabaseDATASUBMISSIONGUIDE

Version1.2(withclarifications)

Output I wish to grab like:

Answer 1

This is the issue with pyPDF2, the reason is PyPDF doesn't read newline character. Alternately you can pdftotext

Simple and clean, you can loop over pages or get extract one page.

import io
import requests
import pdftotext
URL = 'http://www.ct.gov/hix/lib/hix/CT_DSG_-12132014_version_1.2_%28with_clarifications%29.pdf'
res = requests.get(URL)
f = io.BytesIO(res.content)
pdf = pdftotext.PDF(f)
print(pdf[0])
# Iterate over all the pages
# for page in pdf:
#     print(page)

Answer 2

I would suggest PDFMiner if installing other packages causes a dependency issue.

You can install it for python 3.7 by doing pip install pdfminer.six , I've already tested and its working on my python 3.7.

The code for getting page 0 is as follows

import io
import requests
from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.pdfpage import PDFPage
from pdfminer.converter import XMLConverter, HTMLConverter, TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfdocument import PDFDocument
from pdfminer.pdfparser import PDFParser

URL = 'http://www.ct.gov/hix/lib/hix/CT_DSG_-12132014_version_1.2_%28with_clarifications%29.pdf'

res = requests.get(URL)
fp = io.BytesIO(res.content)

rsrcmgr = PDFResourceManager()
retstr = io.StringIO()
codec = 'utf-8'
laparams = LAParams()
device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
interpreter = PDFPageInterpreter(rsrcmgr, device)

page_no = 0
for pageNumber, page in enumerate(PDFPage.get_pages(fp)):
    if pageNumber == page_no:
        interpreter.process_page(page)

        data = retstr.getvalue()

print(data.strip())

Outputs

The good thing about PDFMiner is that it reads your pages directly and it focuses entirely on getting and analyzing text data.
