用python实现PDF解密打印文件

import pikepdf
with pikepdf.open("原打印加密文件.pdf") as pdf:
    num_pages = len(pdf.pages)
    del pdf.pages[-1]
    pdf.save("新转存非加密文件.pdf")

import pikepdf
import os
inFile = input("请输入PDF数据文件夹：")
outFile = input("请输入新PDF输出文件夹：")
filelist = os.listdir(inFile)
for file in filelist:
    if file.endswith(".pdf")and ("~$" not in file):
        filePath = inFile + "\\"+file
        print ("正在转换：",filePath)
        with pikepdf.open(filePath) as pdf:
            num_pages = len(pdf.pages)
            del pdf.pages[-1]
            pdf.save(outFile + "\\"+ file)
