PDF分割--可脱离python环境执行，可传参数，可弹窗的PC端小工具

1.首先，实现功能源码

#!/usr/bin/env python
# coding=utf-8
import tkinter.messagebox
from tkinter import *
from PyPDF2 import PdfFileReader, PdfFileWriter
import re

# 设置全局变量
filename=""
pdf_input=""
fp_read_file=""
page_count=0
# PDF文件分割
def split_pdf( out_detail):
    try:
        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))
                # print(detail)
                # 如果取到的内容包括“the file to be split is :”
                line_wold = "the file to be split is :"
                if line_wold in detail:
                    #  切割获取文件名：
                    rule = r'the file to be split is :(.*?.pdf)'
                    filename = re.findall(rule, detail)[0].strip()
                    print(filename)
                    fp_read_file = open(filename, '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("该文件一共"+str(page_count)+"页")  # 打印页数

                    print(filename)
                    print("获取文件名完成，开始分割")
                    continue
                pages, write_file = detail.split()  # 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'{write_file}.pdf'
                # liststr=list(map(int, pages.split('-')))
                # print(type(liststr))
                try:
                    start_page, end_page = list(map(int, pages.split('-')))  # 将字符串数组转换成整形数组
                    print(start_page)
                except :
                    tkinter.Tk().withdraw()
                    tkinter.messagebox.showwarning("配置文件", "页数为空或不是正整数，请检查配置文件")
                    return
                if start_page < 1:
                    # 隐藏主窗口
                    tkinter.Tk().withdraw()
                    # 消息框提示消息
                    tkinter.messagebox.showwarning("配置文件","起始页面不能为0！请重新编辑页面")
                    return
                start_page -= 1
                # 如果输入页数大于最大页数，则最大页数
                if end_page > page_count:
                    end_page=page_count
                    # 隐藏主窗口
                    tkinter.Tk().withdraw();
                    tkinter.messagebox.showwarning("配置文件", "分割页数超过了PDF的页数，已调整为结束页为最后一页"+str(page_count))
                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')  # 这个部分其实可以不用try，前面已经处理过了
    except Exception as e:
        print(e)
    finally:
        fp_read_file.close()

split_pdf( 'configure.txt')

2.实现打包成脱离python环境的.EXE程序
