python及pycharm的安装

安装之前

1.计算机组成结构

• cpu，硬盘，内存，输入输出设备，主板，电源
• 计算机操作系统

2.硬件之间的协作关系

• cpu运算完后给操作系统，专业术语：指令

3.写的代码怎么运行起来

• 键盘中输入a之后发生的事情
  • 键盘-cpu-操作系统-显卡-显示器

4.什么是编程语言

• 编程语言是用来定义计算机程序的形式语言

5.高级编程语言之间的区别

• 解释型：python,PHP
  • 代码一行一行解释，最后解释完生成PYC文件，这个c语言的文件，c语言再去编译它
• 编译型：c，java
  • 写完代码，整片封装成一个小箱子，交给cpu直接就能起反应
