def merge_pdfs(pdf_list, output_filename):
merger = PdfMerger()
for pdf in pdf_list:
merger.append(pdf)
merger.write(output_filename)
merger.close()
print(f"✅ Merged PDF saved as: {output_filename}")
if __name__ == "__main__":
files = [f for f in os.listdir() if f.endswith('.pdf')]
print("📄 PDFs found:", files)
merge_pdfs(files, "merged_output.pdf")
