I have several Pdfs that I want to merge together. To do this I referenced this https://pythonhosted.org/PyPDF2/PdfFileMerger.html#PyPDF2.PdfFileMerger.write Documentation as well as this Merge PDF files post as reference. My code reads from the the directory where my pdfs lie and tries to write the new pdf into another directory
def concatenate_pdfs(path_to_pdf_dir, output_dir):
"""merge all the pdfs that lie in output_dir into one pdf and store it in path_to_pdf_dir"""
merger = PyPDF2.PdfFileMerger()
for filepath in glob(f'{output_dir}*.pdf'):
merger.append(filepath)
merger.write(f'{path_to_pdf_dir}/output.pdf')
merger.close()
The new pdf is created but only with the first pdf that gets parsed.
The same problem occurs when I do it like this:
def concatenate_pdfs(path_to_pdf_dir, output_dir):
"""merge all the pdfs that lie in output_dir into one pdf and store it in path_to_pdf_dir"""
merger = PyPDF2.PdfFileMerger()
f1 = 'path_to_first_pdf'
f2 = 'path_to_second_pdf'
f3 = 'path_to_nth_pdf'
merger.append(f1)
merger.append(f2)
merger.append(f3)
merger.write(f'{path_to_pdf_dir}/output.pdf')
merger.close()
In this case only f1 gets written to my output.pdf
