How to read all pdf files in a directory and convert to text file using tesseract python 3?
The below code is for reading one pdf file and convert to text file.
But i want to read all pdf files in a directory and convert to text file using tesseract python 3
from PIL import Image
import pytesseract
import sys
from pdf2image import convert_from_path
import os
pdf_filename = "pdffile_name.pdf"
txt_filename = "text_file_created.txt"
def tesseract(pdf_filename,txt_filename):
PDF_file = pdf_filename
pages = convert_from_path(PDF_file, 500)
image_counter = 1
for page in pages:
pdf_filename = "page_"+str(image_counter)+".jpg"
page.save(pdf_filename, 'JPEG')
image_counter = image_counter + 1
filelimit = image_counter-1
outfile = txt_filename
f = open(outfile, "a",encoding = "utf-8")
for i in range(1, filelimit + 1):
pdf_filename = "page_"+str(i)+".jpg"
text = str(((pytesseract.image_to_string(Image.open(pdf_filename)))))
text = text.replace('-\n', '')
f.write(text)
f.close()
f1 = open(outfile, "r",encoding = "utf-8")
text_list = f1.readlines()
return text_list
tesseract(pdf_filename,txt_filename)`enter code here`
i have code for reading pdf files in a directory but i dont know to combine this code with above code
def readfiles():
os.chdir(path)
pdfs = []
for file_list in glob.glob("*.pdf"):
print(file_list)
pdfs.append(file_list)
readfiles()
Simply convert the variable pdf_filename
to a list using this code snippet:
import glob
pdf_filename = [f for f in glob.glob("your_preferred_path/*.pdf")]
which will get you all the pdf files you want and store it into a list.
Or simply use any of the methods posted here:
How do I list all files of a directory?
Once you do that, you now have a list of pdf files.
Now iterate over the list of pdfs, one at a time, which will give you a list of test files.
You can use it something like this code snippet:
for one_pdf in pdf_filename:
#* your code to convert the files *#
Hope this helps.
