Python是纯粹的自由软件,源代码和解释器CPython遵循GPL(GNUGeneral Public License)协议。Python语法简洁清晰,特色之一是强制用空白符(white space)作为语句缩进。 根据PEP的规定,必须使用4个空格来表示每级缩进。 Python是一个高层次的结合了解释性、编译性、互动性和面向对象的脚本语言。
Python语言比起C++、Java等主流语言,语法更简洁,也更接近英语,对编程世界的新人还是很友好的,这也是其显著优点。最近总有人问我Python相关的问题,这些问题也偏基础,自古有句话,授人以鱼不如授人以渔,刚好趁五一时间总结了几篇Python的知识点,帮助小伙伴成功入坑Python,将这门工具语言顺利掌握起来。 Python常用数据...
