PDF 拆分/合并

不会真的有人会去下载那些广告免费，实则要收会员费的黑心软件来进行PDF的拆分合并吧？？？

在下载两个均不能免费实现PDF自由拆分、合并，以及PDF打印方式会增加文件大小的情况下，一个合格的程序员肯定不能向不良商家低头，所以使用PyPDF2实现这些功能，并给大家分享一个简单、易用、易懂的python小程序。

from PyPDF2 import PdfFileReader, PdfFileMerger, PdfFileWriter

def merge(input1,input2,output):

    file_merger = PdfFileMerger()
    file_merger.append(input1)
    file_merger.append(input2)
    file_merger.write(output)

def split(input,output,start_page, end_page):
    try:
        read_file = input
        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("该文件共有{}页".format(page_count))  # 打印页数

        try:
            print(f'开始分割{start_page}页-{end_page}页，保存为{output}......')
            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(output, 'wb') as sub_fp:
                pdf_output.write(sub_fp)
            print(f'完成分割{start_page}页-{end_page}页，保存为{output}!')
        except IndexError:
            print(f'分割页数超过了PDF的页数')
        # fp.close()
    except Exception as e:
        print(e)


if __name__ == '__main__':
    input1 = open(r"1.pdf", "rb") #打开第一个PDF文件
    input2 = open(r"2.pdf", "rb") #打开第二个PDF文件
    output=r'submit.pdf'
    merge(input1,input2,output)

    # input = r"submit.pdf"  #打开第二个PDF文件
    # output= r'1.pdf'
    # split(input,output,9,35) # start 起始页 从0 开始算，end 是尾页从1开始算
