Ubuntu的安装步骤（安装python-pypdf）

Question

我使用以下代码来读取pdf文件，但它没有读取它。可能是什么原因？

>>> import os 

>>> from PyPDF2 import PdfFileReader, PdfFileWriter

>>> path = "/Users/Rahul/Desktop/Dfiles/"

>>> dirs = os.listdir( path )

>>> directory = "/Users/Rahul/Desktop/Dfiles/106_2015_34-76357.pdf"

>>> f = open(directory, 'rb')

>>> reader = PdfFileReader(f)

>>> contents = reader.getPage(0).extractText().split('\n')

>>> f.close()

>>> print contents

输出是[u'']而不是阅读内容。

Answer 1

import re
import PyPDF2

pdfFileObj = open('E://drive-download-20171015T225604Z-001/test_case/test2/try/xyz.pdf', 'rb')
pdfReader = PyPDF2.PdfFileReader(pdfFileObj)
print("Number of pages:-"+str(pdfReader.numPages))
num = pdfReader.numPages
i =0
while(i<num):
    pageObj = pdfReader.getPage(i)
    text=pageObj.extractText()
    text1 = text.lower()
    for line in text1:
        if(re.search("abc",line)):
            print(line)
    i= i+1

我用它来逐页迭代pdf并在其中搜索关键术语并进一步处理。

可能这可以帮助您阅读PDF。

import pyPdf
def getPDFContent(path):
    content = ""
    pages = 10
    p = file(path, "rb")
    pdf_content = pyPdf.PdfFileReader(p)
    for i in range(0, pages):
        content += pdf_content.getPage(i).extractText() + "\n"
    content = " ".join(content.replace(u"\xa0", " ").strip().split())
    return content

Answer 3

我认为您需要指定光盘名称，它在您的目录中缺失。例如＆＃34; D：/Users/Rahul/Desktop/Dfiles/106_2015_34-76357.pdf"。我试过，我可以毫无问题地阅读。

或者，如果您想使用未与目录关联的os模块找到文件路径，可以尝试以下操作：

from PyPDF2 import PdfFileReader
import os

def find(name, path):
    for root, dirs, files in os.walk(path):
        if name in files:
            return os.path.join(root, name)

directory = find('106_2015_34-76357.pdf', 'D:/Users/Rahul/Desktop/Dfiles/')

f = open(directory, 'rb')

reader = PdfFileReader(f)

contents = reader.getPage(0).extractText().split('\n')

f.close()

print(contents)

要从目录中的多个文件夹中读取文件，可以使用以下代码- 该示例用于读取pdf文件：

import os
from tika import parser

path = "/usr/local/" # path directory
directory=os.path.join(path)
for r,d,f in os.walk(directory): #going through subdirectories
    for file in f:
        if ".pdf" in file:  # reading only PDF files
            file_join = os.path.join(r, file)   #getting full path 
            file_data = parser.from_file(file_join)     # parsing the PDF file 
            text = file_data['content']               # read the content 
            print(text)                  #print the content

Answer 5

def getTextPDF(pdfFileName,password=''):
    import PyPDF2
    from PyPDF2 import PdfFileReader, PdfFileWriter
    from nltk import sent_tokenize
    """ Extract Text from pdf  """
    pdf_file=open(pdfFileName,'rb')
    read_pdf=PyPDF2.PdfFileReader(pdf_file)
    if password !='':
        read_pdf.decrypt(password)
    text=[]
    for i in range(0,read_pdf.getNumPages()):
        text.append(read_pdf.getPage(i).extractText())
    text = '\n'.join (text).replace("\n",'')
    text = sent_tokenize(text)
    return text

你好Rahul Pipalia，

如果没有在python中安装PyPDF2，请在使用此模块后首先安装PyPDF2。

Ubuntu的安装步骤（安装python-pypdf）

首先，打开terminal
类型sudo apt-get install python-pypdf

您的Probelm解决方案

请尝试以下代码，

# Import Library
import PyPDF2

# Which you want to read file so give file name with ".pdf" extension
pdf_file = open('Your_Pdf_File_Name.pdf')
read_pdf = PyPDF2.PdfFileReader(pdf_file)
number_of_pages = read_pdf.getNumPages()

#Give page number of the pdf file (How many page in pdf file).
# @param Page_Nuber_of_the_PDF_file: Give page number here i.e 1
page = read_pdf.getPage(Page_Nuber_of_the_PDF_file)

page_content = page.extractText()

# Display content of the pdf
print page_content
