<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">此排行榜排名基于互联网上有经验的程序员、 课程和第三方厂商的数量。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">因此呢</span>,其权威性较为<span style="color: black;">明显</span>,<span style="color: black;">亦</span>是预测<span style="color: black;">将来</span>编程语言流行度的一个风向标。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">另一</span>,<span style="color: black;">按照</span> TIOBE 的 Python 指数来看,Python依然保持着强劲的发展态势,隐<span style="color: black;">大概</span>超越 Java 与 C 语言之势。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">因此</span>,趁着近期宅在家,多花点时间学习Python,既能给简历加分,<span style="color: black;">亦</span>能紧跟上这个高速发展的信息时代。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在我往期的推文中,<span style="color: black;">相关</span>于Python学习的书籍<span style="color: black;">举荐</span>,<span style="color: black;">例如</span>《Python从入门到实践》《笨办法学Python》《 Python Cookbook》等,都是不错的入门和进阶学习书籍。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">但看书,看视频等学习办法,都只是辅助<span style="color: black;">功效</span>,学好Python,最重要的还是<strong style="color: blue;">多敲代码,多刷题</strong>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">不<span style="color: black;">晓得</span>怎么找题刷题的小伙伴,<span style="color: black;">能够</span><span style="color: black;">瞧瞧</span>我今天给<span style="color: black;">大众</span>带来的<strong style="color: blue;">《Python百题大冲关》</strong>。</p>
