PDF file not created when program is run [closed]-CodePudding

I am trying to put a watermark on a pdf but when I run the code it does nothing , It does not create the output file what did I missed?

# pdf watermarkerV2

import PyPDF2


template = PyPDF2.PdfFileReader(open('super.pdf', 'rb'))
watermark = PyPDF2.PdfFileReader(open('wtr.pdf', 'rb'))
output = PyPDF2.PdfFileWriter()

for i in range(template.getNumPages()):
    page = template.getPage(i)
    page.mergePage(watermark.getPage(0))
    output.addPage(page)

    with open('watermarked.pdf', 'wb') as file:
        output.write(file)

CodePudding user response：

Your with clause was within the for loop.

This will work:


import PyPDF2


template = PyPDF2.PdfFileReader(open('super.pdf', 'rb'))
watermark = PyPDF2.PdfFileReader(open('wtr.pdf', 'rb'))
output = PyPDF2.PdfFileWriter()

for i in range(template.getNumPages()):
    page = template.getPage(i)
    page.mergePage(watermark.getPage(0))
    output.addPage(page)

with open('watermarked.pdf', 'wb') as file:
    output.write(file)
