使用 PyPDF2 将来自两个不同文件夹的特定名称的 PDF 合并

您说“合并”的意思是“合并”吗？

如果是这样的话，

假设 folder1 包含"PID-01.pdf"并且 folder2 包含"FNN-PID-01.pdf"。

import os
from PyPDF2 import PdfFileMerger, PdfFileReader
folder1 = "/your/path/to/folder1/"
folder2 = "/your/path/to/folder2/"
merged_folder = "/your/path/to/merged/folder/"

f1_files = os.listdir(folder1) # ['PID-01.pdf','PID-02.pdf'...etc]
f2_files = os.listdir(folder2) # ['FNN-PID-01.pdf','FNN-PID-02.pdf'...etc]

def pdf_merger(f1,f2):
    merger = PdfFileMerger()
    f1_content = PdfFileReader(file(os.path.join(merged_folder,f1), 'rb'))
    f2_content = PdfFileReader(file(os.path.join(merged_folder,f2), 'rb'))
    merger.append(f1_content)
    merger.append(f2_content)
    out = os.path.join(merged_folder,f"merged-{f1}")
    merger.write(out)

#below code will iterate each file in folder1 and checks if those               
#folder2 filename string "FNN-PID-01.pdf" contains substring "PID-01.pdf"
#if matchs, the 2 matching files are merged and saved to merged_folder

for file1 in f1_files : 
    for file2 in f2_files: 
        if file1 in file2: 
            pdf_merger(file1,file2)

您可以只迭代文件并使用正则表达式编写自己的匹配模式以进行高级使用。
