python3 使用PyPDF2分割pdf【附代码】

今天爱分享给大家带来python3 使用PyPDF2分割pdf【附代码】，希望能够帮助到大家。

首先需要安装:

pip install PyPDF2

批量切割
然后利用下面的代码：

from PyPDF2 import PdfFileReader, PdfFileWriter
 
 
# PDF文件分割
def split_pdf(read_file, out_detail):
    try:
        fp_read_file = open(read_file, 'rb')
        pdf_input = PdfFileReader(fp_read_file)  # 将要分割的PDF内容格式话
        page_count = pdf_input.getNumPages()  # 获取PDF页数
        print(page_count)  # 打印页数
 
        with open(out_detail, 'r',True,'utf-8')as fp:
            # print(fp)
            txt = fp.readlines()
            # print(txt)
            for detail in txt:  # 打开分割标准文件
                # print(type(detail))
                pages= detail.strip() # 空格分组
               #  write_file, write_ext = os.path.splitext(write_file)  # 用于返回文件名和扩展名元组
                pdf_file = f'{pages}.pdf'
                # liststr=list(map(int, pages.split('-')))
                # print(type(liststr))
                start_page, end_page = list(map(int, pages.split('-')))  # 将字符串数组转换成整形数组
                start_page -= 1
                try:
                    print(f'开始分割{start_page}页-{end_page}页，保存为{pdf_file}......')
                    pdf_output = PdfFileWriter()  # 实例一个 PDF文件编写器
                    for i in range(start_page, end_page):
                        pdf_output.addPage(pdf_input.getPage(i))
                    with open(pdf_file, 'wb') as sub_fp:
                        pdf_output.write(sub_fp)
                    print(f'完成分割{start_page}页-{end_page}页，保存为{pdf_file}!')
                except IndexError:
                    print(f'分割页数超过了PDF的页数')
        # fp.close()
    except Exception as e:
        print(e)
    finally:
        fp_read_file.close()
 
 
split_pdf('./高考模拟卷（6套）/试卷/2020模拟卷语文·试卷.pdf', 'config.txt')

config.txt为起始页文件，我的config.txt文件为：

1-4
5-8
9-12
13-16
17-20
21-24

切割指定页面的pdf

from PyPDF2 import PdfFileReader, PdfFileWriter
 
def split_single_pdf(read_file,start_page,end_page,pdf_file):
    fp_read_file = open(read_file, 'rb')
    pdf_output = PdfFileWriter()  # 实例一个 PDF文件编写器
    pdf_input = PdfFileReader(fp_read_file)  # 将要分割的PDF内容格式话
    for i in range(start_page, end_page):
        pdf_output.addPage(pdf_input.getPage(i))
    with open(pdf_file, 'wb') as sub_fp:
        pdf_output.write(sub_fp)
    print(f'完成分割{start_page}页-{end_page}页，保存为{pdf_file}!')
 
pdf_name='Automatic Chinese Spelling Checking and Correction Based on Character-Based Pre-trained Contextual Representations.pdf'
split_single_pdf('2019_Book_NaturalLanguageProcessingAndCh.pdf',569,579,pdf_name)
