I am trying to print out the sentence for where the word was found but it just prints out that it founded the word on that page number.

import os
from pdfreader import SimplePDFViewer, PageDoesNotExist

def search_in_file(fname, search_words):
    fd = open(fname, "rb")
    viewer = SimplePDFViewer(fd)
    try:
        while True:
            viewer.render()
            text = "".join(viewer.canvas.strings)
            for word in search_words:
                if word in text:
                    print("The word '{}' was found in '{}' on page {}".format(word, fname, viewer.current_page_number))
            viewer.next()
    except PageDoesNotExist:
        pass

# define keywords
search_words = ['python', 'aws', 'sql']

# define directory
directory = "./"

# Loop through all PDFs in specified directory:
for fname in os.listdir(directory):
    if fname.endswith(".pdf"):
        search_in_file(fname, search_words)

Remember to:

Ask your Python question, not if you can ask or if there's an expert who can help.
Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

can you show some output?

#

You're saying it's not printing word in your print statement?

he word 'python' was found in '60-mercurymagazines19-w_mmed11-rPiMvnTCyRuL8g_3GQYjCA.pdf' on page 20
The word 'aws' was found in '60-mercurymagazines19-w_mmed11-rPiMvnTCyRuL8g_3GQYjCA.pdf' on page 28
The word 'python' was found in '60-mercurymagazines19-w_mmed11-rPiMvnTCyRuL8g_3GQYjCA.pdf' on page 55
The word 'aws' was found in '60-mercurymagazines19-w_mmed11-rPiMvnTCyRuL8g_3GQYjCA.pdf' on page 71

#

I need for it to print out the entire sentence where it was founded to be

#

Than I do get this error

Looks like you need to actually load the page then render it.

open maple Feb 24, 2024, 1:44 AM

#

If you can help me with that

shrewd ermine Feb 24, 2024, 1:45 AM

#

I've never used the module before sorry.

#

it seems straightforward though

#

that example navigates to page 8 then renders it

open maple Feb 24, 2024, 1:46 AM

#

Yes but like what senetcne

#

Did the code work for you

shrewd ermine Feb 24, 2024, 1:46 AM

#

You said you wanted to show the page where you find the word?

#

I haven't run any code.

open maple Feb 24, 2024, 1:47 AM

#

Okay

shrewd ermine Feb 24, 2024, 1:47 AM

#

find the page with the word. 2. navigate to that page and render it

#

idk if you can like highlight it or anything with the module

#

the api reference is at that website though so you can poke around

open maple Feb 24, 2024, 1:48 AM

#

Okay as thank you as I done this before but cannot remember without seeing my repvious code at work

shrewd ermine Feb 24, 2024, 1:48 AM

#

Well that tutorial seems pretty thorough so I think if you spend some time with it you'll figure it out.

open maple Feb 24, 2024, 1:48 AM

Okay

@shrewd ermine

#

Founded this code but I am getting an idnex out of range ror the pageNumbers

#

import PyPDF2
import re
import glob
 
file_list = glob.glob("/Users/kevineldridge/Documents/*.pdf")
failed_pages = []
 
# define search string
String = input("Search: ")
 
for j in file_list:
    # open the pdf file
    print('-'*100)
    print("Opening: \n"+str(j)+"\n")
    obj = PyPDF2.PdfReader(j)
    # get number of pages
    NumPages = len(obj.pages) 
    failed_pages = []
    # extract text and do the search
    for i in range(0, NumPages):
        PageObj = obj.pages[i]
        try:
            Text = PageObj.extractText()
        except:
            Text = ''
            failed_pages.append(i)
            pass
        ResSearch = re.search(String, Text)
        if ResSearch:
            print("Found on page: "+str(i)+" "+(str(Text[ResSearch.start()-30:ResSearch.end()+30])).replace("\n", " "))
    print("Failed pages:"+str(failed_pages))
input("prompt: ")

shrewd ermine Feb 24, 2024, 2:13 AM

#

ah

#

Why not try to write it yourself? That uses an entirely different module.

open maple Feb 24, 2024, 2:14 AM

#

I will do that as it does make sense

#

for i in range(0, NumPages):
PageObj = obj.pages[i]
try:
Text = PageObj.extractText()
