如何用python插入独创性声明

pip install PyPDF2

# 定义输出对象
outputName = 'output.pdf'
output = PdfFileWriter()
# 定义读取对象
thesisPDF = PdfFileReader(open(thesisName,'rb'))
insertPDF = PdfFileReader(open(insertName,'rb'))
N_page = thesisPDF.getNumPages()
pos = int(input('论文一共有"%d"页，请输入需要插入的位置：'%N_page))

# 将声明插入到指定页面
for i in range(pos):
  output.addPage(thesisPDF.getPage(i))
output.addPage(insertPDF.getPage(0)) # 插入
for i in range(pos,N_page):
  output.addPage(thesisPDF.getPage(i)) 

# 保存插入后的结果
output.write(open(outputName,'wb'))

# -*- coding: utf-8 -*-
