以终为始:学python后的几个用途


    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">学编程不是一个容易的事,<span style="color: black;">必要</span>有一个很好的学习动力,<span style="color: black;">例如</span>,考个计算机证<span style="color: black;">能够</span>给简历加分,<span style="color: black;">处理</span>某个工作中的<span style="color: black;">实质</span>问题。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">2019年,<span style="color: black;">起始</span>接触吴恩达的<span style="color: black;">设备</span>学习课程,里面用的是Python,看到后面有些吃力,决定学习一下Python,搜了一下<span style="color: black;">发掘</span>,Python还是NCRE计算机等级考试的科目之一,立即报名,为了逼自己把python书看完,不浪费报名费。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">9月份,<span style="color: black;">做为</span>30多岁的大叔,和大学生们<span style="color: black;">一块</span>参加计算机等级考试</p>

    <div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/f16acee6ba21487e8fb89363f17e2d4a~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1723902629&amp;x-signature=GRmM5pWbYPNg0xLEHtEb6driNTA%3D" style="width: 50%; margin-bottom: 20px;"></div>
    <div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/e539e1df37734f60bfc4b5ba4db7b107~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1723902629&amp;x-signature=Cl9ZRUUnlZ6JsZclXeKYGFqwHoM%3D" style="width: 50%; margin-bottom: 20px;"></div>
    <div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/72df11b0d45c43acbd2fd9afa7947417~noop.image?_iz=58558&amp;from=article.pc_detail&amp;lk3s=953192f4&amp;x-expires=1723902629&amp;x-signature=Hr0K3gvaExlhrbqOyzqucyruA0E%3D" style="width: 50%; margin-bottom: 20px;"></div>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">考完了python,<span style="color: black;">起始</span>在网上搜,<strong style="color: blue;">学了Python能干啥?</strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">前提<span style="color: black;">要求</span>:能用软件等做的,<span style="color: black;">尽可能</span><span style="color: black;">不消</span>Python。</strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">发掘</span>了几个用途:</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">1.NLP自然语言处理:分析用户评论</span></strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">例如</span>,新上市一个车型,<span style="color: black;">资讯</span>下面会有一大堆人在<span style="color: black;">评估</span>,这些<span style="color: black;">评估</span>是正面还是<span style="color: black;">消极</span>(情感分析)?几百条评论的词频是什么?这一大堆评论的摘要是什么?这个得用python的NLP包,excel绝对做不了。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">2.画<span style="color: black;">繁杂</span>图</span></strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">例如</span>三维散点图,这个excel做不了,<span style="color: black;">不外</span>三维散点图没啥实用价值,还是二维的<span style="color: black;">可靠</span>。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">3.理解自动驾驶课程</span></strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">看Udacity上的自动驾驶课程,里面<span style="color: black;">触及</span><span style="color: black;">怎样</span>自动识别<span style="color: black;">阻碍</span>物、车道线等,比较容易理解,当然只能用来<span style="color: black;">认识</span>自动驾驶的理论框架,离<span style="color: black;">开发</span>自动驾驶差的太远。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">4.自动化的思想</span></strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">凡是遇到重复的、有规律的工作内容,我<span style="color: black;">第1</span>时间会去搜<span style="color: black;">怎样</span>自动化,节省了不少时间。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">有个python办公自动化的课程,用<strong style="color: blue;">python自动生成合同、工资条、自动群发邮件等</strong>,我暂时没这方面需求,<span style="color: black;">因此</span><span style="color: black;">亦</span>没学。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">不消</span>Python做的事:</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">1、爬虫</strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">咱是业余爬虫选手,爬个<span style="color: black;">资讯</span>、论坛帖子、车型参数等,爬虫软件就够用了,可视化界面简单易懂,弄一堆代码还是算了。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">2、数据分析可视化、自动化</strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">日前</span>的业务还没碰到用python来分析数据,Tableau、PowerBI就挺好。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">3、调查问卷统计</strong></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">几万以内的样本量,用SPSS就行,样本量太大的我还没遇到过。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">总结,<span style="color: black;">微X</span><span style="color: black;">伴侣</span>圈里关于python的培训<span style="color: black;">宣传</span>无处不在,神吹的<span style="color: black;">占多数</span>,大部分宣传的功能用excel等软件就能<span style="color: black;">处理</span>,当重复性的工作<span style="color: black;">没法</span>用软件<span style="color: black;">处理</span>时,再用Python吧,毕竟<span style="color: black;">针对</span>非计算机专业的人<span style="color: black;">来讲</span>,Windows界面的软件比一大堆代码好看多了。</p>
