python工具

一、使用场景

　　某些配置文件里有一些特定的字符，而这些字符恰巧需要我们采集出来，然后输出到另外一个窗口做展示时，可以使用该工具。

本例的演示则提取配置文件中的【姓名：黄蓉 女 九阴真经、姓名：郭靖 男 弹指神功】两行读取出来，读取其他内容也可以，更改相应参数即可。

二、实验文件

　　测试脚本：fielread.py

　　配置文件：john.conf

三、测试脚本代码

#! /usr/bin/env python3
# -*- coding:UTF-8 -*-

from tkinter import *
import tkinter

ss = input('请输入搜索内容的开始首字符：')
es = input('请输入搜索内容的结束首字符：')
fp = input('请输入要搜索文件的路径：')

def fetch(startStr,endStr,filePath):
    newLi = []
    with open(filePath,'r',encoding='utf-8') as f :
        flag = False
        for line in f:
            if line.strip().startswith(startStr):
                flag = True

            if line.strip().startswith(endStr):
                flag = False

            if flag and line.strip():
                newLi.append(line.strip())
    return newLi

info = fetch(ss,es,fp)  # 调用fetch函数进行内容匹配，结果返回列表保存到info中

# [1]控制台打印输出
result = '
'.join(info)
print(result)

# [2]alert弹窗打印输出
root = Tk() # 创建窗口对象的背景颜色
new_info = Listbox(root)
for item in info:
    new_info.insert(0,item)
new_info.pack()
root.mainloop()

四、配置文件内容

void init()
{
    password_length = 16; /* Change this to match config */

    int c, i;

    c = '0'; i = 0; while (c <= '9') numbers[i++] = c++;
    c = 'a'; i = 0; while (c <= 'z') lowers[i++] = c++;
    c = 'A'; i = 0; while (c <= 'Z') uppers[i++] = c++;

    /* symbols */
    i = 0;
    symbols[i++] = '!'; symbols[i++] = '@'; symbols[i++] = '#'; symbols[i++] = '$';
    symbols[i++] = '%'; symbols[i++] = '^'; symbols[i++] = '&'; symbols[i++] = '*';
    symbols[i++] = '('; symbols[i++] = ')'; symbols[i++] = '~'; symbols[i++] = '-';

    boundaries_charclass[i++] = 536870912; boundaries_charclass[i++] = 1073741824;
    boundaries_charclass[i++] = 1610612736; boundaries_charclass[i++] = 2147483647;

    姓名：黄蓉 女 九阴真经
    姓名：郭靖 男 弹指神功

    备注：
