python编程例子有哪些?
python编程经典例子:
1、画爱心表白、图形都是由一系列的点(X,Y)构成的曲线,由于X,Y满足一定的关系,所以就可以建立模型,建立表达式expression,当满足时,两个for循环(for X in range;for Y in range)就会每行每列的打印。
2、快递查询工具、此Python小项目需要用到json与requests两个库,还需调用API。
3、用python编程完成图像识别、鼠标模拟,需要调用OpenCV框架。
扩展资料:
Python的设计目标之一是让代码具备高度的可阅读性。它设计时尽量使用其它语言经常使用的标点符号和英文单字,让代码看起来整洁美观。它不像其他的静态语言如C、Pascal那样需要重复书写声明语句,也不像它们的语法那样经常有特殊情况和意外。
Python开发者有意让违反了缩进规则的程序不能通过编译,以此来强制程序员养成良好的编程习惯。并且Python语言利用缩进表示语句块的开始和退出,而非使用花括号或者某种关键字。增加缩进表示语句块的开始,而减少缩进则表示语句块的退出,缩进成为了语法的一部分。
