1.PDF文件的合并
import PyPDF2

fs = [‘1.pdf’, ‘2.pdf’]
m = PyPDF2.PdfFileMerger()
for f in fs:
m.append(PyPDF2.PdfFileReader(f))
m.write(‘1.pdf’)
print(m)
2.PDF文件的加密
import PyPDF2

with open(‘ori_file.pdf’,‘rb’) as pdffile:
pdfreader = PyPDF2.PdfFileReader(pdffile)
pdfwriter =PyPDF2.PdfFileWriter()
for page in range(pdfreader.numPages):
pdfwriter.addPage(pdfreader.getPage(page))
pdfwriter.encrypt(str(1234))
with open(‘new_file.pdf’,‘wb’) as return_pdf:
pdfwriter.write(return_pdf)
3.获取PDF文件的加密密码（前提加密密码都是数字）
import PyPDF2
Password = 1
with open(‘1.pdf’,‘rb’) as pdfFile:
pdfReader = PyPDF2.PdfFileReader(pdfFile)
while Password:
if pdfReader.decrypt(str(Password)):
# pdfFile = pdfReader.getPage(0)
# print(pdfFile.extractText())
print(Password)
break
else:
Password = Password + 1
