其实,很多个程序员都是从不会到会,每种知识也是从基础到复杂,大家都是从零基础开始的,有的学员英语和数字基础也很差,从一点都不了解编码到现在非常熟练使用Python。

一般Python编程语言的初学者,要从基础数据类型开始了解Python的动作机制,再到各个类型的操作方法的掌握,就可以对Python有一个比较好的入门了,这个过程根据每个人的不同,大约需要几周到数月。

Python是一种什么语言?

Python是一种计算机程序设计语言。你可能已经听说过很多种流行的编程语言,比如非常难学的C语言,非常流行的Java语言,适合初学者的Basic语言,适合网页编程的JavaScript语言等,Python是他们其中的一种。

首先,我们普及一下编程语言的基础知识。用任何编程语言来开发程序,都是为了让计算机干活,比如下载一个MP3,编写一个文档等,而计算机干活的CPU只认识机器指令,所以,尽管不同的编程语言差异极大,最后都得“翻译”成CPU可以执行的机器指令。而不同的编程语言,干同一个活,编写的代码量,差距也很大。

比如,完成同一个任务,C语言要写1000行代码,Java只需要写100行,而Python可能只要20行。

所以Python是一种相当高级的语言。

学习Python难吗?

是不是越低级的程序越难学,越高级的程序越简单?

表面上来说,是的。

但是,在非常高的抽象计算中,高级的Python程序设计也是非常难学的,所以,高级程序语言不等于简单。

但是,对于初学者和完成普通任务,Python语言是非常简单易用的。

如果我是小白,我满足什么条件可以学Python呢?

——会使用电脑,但从来没写过程序;

——还记得初中数学学的方程式和一点点代数知识;

——想从编程小白变成专业的软件架构师;

怎样才能在python界占有一席之地呢?

除了上述的三条,还要有:

——全力以赴不间断学习的毅力

——不骄不躁不退缩不认输的决心

学Python后到底能干什么?

爬虫,运维、web开发、应用开发、大数据、数据挖掘、科学计算、机器学习、人工智能、自然语言处理……还可以写很长很长……
