PyPDF2 or indentation issue

[snippsat]

Also indentation always 4-space,never single \ that way in filename Windows.
You open file 2 times in first code.

from PyPDF2 import PdfFileReader, PdfFileWriter
import os

directory = os.listdir("E:/pdf/1")
for file in directory:
    if file.endswith(".pdf"):
        pfile = "E:/pdf/1/" + file
        pdfFile = PdfFileReader(open(pfile, 'rb'))
        page = pdfFile.getPage(0)
        print(page.extractText())
