能让你期末提高十分的python基础复习总结。

Python 基础复习总结
1.基础规则：自带开发工具 IDLE；# 单行注释、三引号多行注释；有固定保留字不可用作变量名；变量名只能字母 / 下划线开头，区分大小写；代码靠缩进分层，遵循输入 - 处理 - 输出模型。
2.数据类型：动态语言，运行才确定变量类型。分数值（整数、浮点数、复数）、布尔、序列（字符串、列表、元组）、集合、字典，各类型可变 / 不可变、有序无序特性不同。
3.运算符与内置函数：包含算术、位、比较、逻辑、成员、身份、赋值七类运算符，括号可调整运算优先级；内置函数可实现求商余、幂运算、取绝对值、四舍五入、进制转换等常用计算。#python#python学习#python教学#大学生#python编程
