Concatenate multiple Pdf using PyPDF2

I am trying to merge multiple pdfs into one. Following is my code:

import PyPDF2
import os
import sys

if not sys.warnoptions:
    import warnings
    warnings.simplefilter("ignore")

pdf_path=r'path'
os.chdir(pdf_path)

output_pdf=input("Enter for output pdf: ")

#Get PDF list
pdfmerge=[]
for pdf_file in os.listdir(pdf_path):
    if pdf_file.endswith('.pdf'):
        pdfmerge.append(pdf_file)

pdfWriter = PyPDF2.PdfFileWriter()

#loop through all PDFs
for pdf_file in pdfmerge:
    pdfFileObj=open(pdf_file,'rb')
    pdfReader = PyPDF2.PdfFileReader(pdfFileObj)

for pageNum in range(pdfReader.numPages):
    pageObj=pdfReader.getPage(pageNum)
    pdfWriter.addPage(pageObj)

#Save PDF
pdfOutput=open(output_pdf+'.pdf','wb')

pdfWriter.write(pdfOutput)
pdfOutput.close()

This code is giving the output pdf but only the last pdf in folder is getting concatenated in the output pdf and the rest are not. What do i change in the code so that all the pdfs in the folder get merged and not just the last pdf

You're missing an indentation when iterating the pages, it should read:

for pdf_file in pdfmerge:
    pdfFileObj=open(pdf_file,'rb')
    pdfReader = PyPDF2.PdfFileReader(pdfFileObj)

    for pageNum in range(pdfReader.numPages):
        pageObj=pdfReader.getPage(pageNum)
        pdfWriter.addPage(pageObj)
