将多个PDF合并为一个PDF

Question

我试图将4个PDF文档合并成1个PDF文档，但是我得到了一个类型错误，它声明我不能将'list‘对象隐式转换为str。如何解决这个问题，以及我在下面尝试的代码是否会将我所有的PDF合并成一个？

# Script to generate a PDF report containing all PDFs
from PyPDF2 import PdfFileMerger
import os

path = 'H:\College Fourth Year\Development Project\Final Year Project 2018\Forensic Reports'

pdf_files = ['Call Log Data Report.pdf','Canonical Address Data Report.pdf', 'Sim Card Data Report.pdf', 'SMS Data Report.pdf']

merger = PdfFileMerger()

for files in pdf_files:
    merger.append(path + pdf_files)
if not os.path.exists(path + 'Full Report.pdf'):
    merger.write(path + 'Full Report.pdf')
merger.close()

# Updated Code
from PyPDF2 import PdfFileMerger
import os

path = r'H:\College Fourth Year\Development Project\Final Year Project 2018\Forensic Reports'

pdf_files = ['Call Log Data Report.pdf','Canonical Address Data Report.pdf', 'Sim Card Data Report.pdf', 'SMS Data Report.pdf']

merger = PdfFileMerger()

for files in pdf_files:
    PdfFileMerger.append(path + files)
if not os.path.exists(path + 'Full Report.pdf'):
    merger.write(path + 'Full Report.pdf')
merger.close()

Answer 1

这条线上

 merger.append(path + pdf_files)

你想

 merger.append(path + files)
