如何在pdfplumber中打开多个文件？

Question

I have multiple PDF files created with Access DB forms. The only way I can extract text from them is using pdfplumber. Here is my code and it works perfectly for just 1 file.

import pdfplumber

with pdfplumber.open('CS_page_1.pdf') as pdf:
    page = pdf.pages[0]
    string = page.extract_text()
    file_name = string[43:48]
    print(file_name)

I need to use this extracted string to rename this file and the 100 other files in the folder. What would be the best way to do it?

Answer 1

Would first build a list of all the pdfs in your folder using glob ( https://docs.python.org/3/library/glob.html ).

Then iterate through each of them- pdfplumb them to obtain the desired string (which you want to rename the file to)- and then rename each individually ( https://www.tutorialspoint.com/python/os_rename.htm ). Something like this:

import glob
import pdfplumber
import os

arr_of_files = (glob.glob("/path/to/pdfs/*.pdf"))

for file in arr_of_files:
    with pdfplumber.open(file) as pdf:
        page = pdf.pages[0]
        string = page.extract_text()
        file_name = string[43:48]
        os.rename(file, file_name)
        

Answer 2

import pdfplumber
import glob
from tqdm.auto import tqdm
for current_pdf_file in tqdm(glob.glob("<pathname>\.pdf")):
    with pdfplumber.open(current_pdf_file) as my_pdf:
         # do other things here?
