How to extract text from pdf in python 3.7.3

Question

I am trying to extract text from a PDF file using Python. My main goal is I am trying to create a program that reads a bank statement and extracts its text to update an excel file to easily record monthly spendings. Right now I am focusing just extracting the text from the pdf file but I don't know how to do so.

What is currently the best and easiest way to extract text from a PDF file into a string? What library is best to use today and how can I do it?

I have tried using PyPDF2 but everytime I try to extract text from any page using extractText(), it returns empty strings. I have tried installing textract but I get errors because I need more libraries I think.

import PyPDF2

pdfFileObj = open("January2019.pdf", 'rb')
pdfReader = PyPDF2.PdfFileReader(pdfFileObj)

pageObj = pdfReader.getPage(0)
print(pageObj.extractText())

This prints empty strings when it should be printing the contents of the page

Answer 1

我尝试了很多方法但都失败了，包括 PyPDF2 和 Tika。我终于找到了对我有用的模块pdfplumber，你也可以试试。

希望这对你有帮助。

import pdfplumber
pdf = pdfplumber.open('pdffile.pdf')
page = pdf.pages[0]
text = page.extract_text()
print(text)
pdf.close()

使用蒂卡对我有用！

from tika import parser

rawText = parser.from_file('January2019.pdf')

rawList = rawText['content'].splitlines()

这使得将银行对帐单中的每一行分别提取到一个列表中非常容易。

如果您正在寻找维护的更大的项目，请查看PyMuPDF。安装它pip install pymupdf并像这样使用它：

import fitz

def get_text(filepath: str) -> str:
    with fitz.open(filepath) as doc:
        text = ""
        for page in doc:
            text += page.getText().strip()
        return text
