Read PDF in Python and convert to text in PDF

问题

I have used this code to convert pdf to text.

input1 = '//Home//Sai Krishna Dubagunta.pdf'
output = '//Home//Me.txt'
os.system(("pdftotext %s %s") %( input1, output))

I have created the Home directory and pasted the source file in it.

The output I get is

And no file with .txt was created. Where is the Problem?

回答1:

Your expression

("pdftotext %s %s") %( input1, output)

will translate to

pdftotext //Home//Sai Krishna Dubagunta.pdf //Home//Me.txt

which means that the first parameter passed to pdftotext is //Home//Sai, and the second parameter is Krishna. That obviously won't work.

Enclose the parameters in quotes:

os.system("pdftotext '%s' '%s'" % (input1, output))

回答2:

There are various Python packages to extract the text from a PDF with Python.

pdftotext

pdftotext package: Seems to work pretty well, but it has no options e.g. to extract bounding boxes

Installation

For Ubuntu:

sudo apt-get install build-essential libpoppler-cpp-dev pkg-config python-dev

Minimal Working Example

import pdftotext

with open("lorem_ipsum.pdf", "rb") as f:
    pdf = pdftotext.PDF(f)

# Iterate over all the pages
for page in pdf:
    print(page)

# Just read the second page
print(pdf.read(2))

# Or read all the text at once
print(pdf.read_all())

PDF miner

Install it with pip install pdfminer.six. A minimal working example is here.

I think pdftotext command takes only one argument. Try using:

os.system(("pdftotext %s") % input1)

and see what happens. Hope this helps.
