=再说学习python 2021=
看完一本书 ,并代码过它,以前就不要再浪费时间看基础了
然后找个项目搞一下以前的那本PY也行或者其它地方找,其实当年也是打过的不过又忘记了吃亏

==python切片步长负数怎么理解==
负数的话最后一个为-1 ,
依然字符串截取遵循“左闭右开”原则，也叫“包左不包右”：

取最后一个
>>> lst[-1]

==斐波那契数列==
<pre>
斐波那契数列的定义

F(0)=0，F(1)=1, F(n)=F(n - 1)+F(n - 2)（n ≥ 2，n ∈ N*）

元组实现我还是不太明白 (fibs[-2] + fibs[-1]) 是最后两项因为 -1 是从右向左数的

fibs = [0, 1]
for i in range(8):
fibs.append(fibs[-2] + fibs[-1])

这能得到一个在指定范围内的斐波那契数列的列表。

#!/usr/bin/python3
# -*- coding: utf-8 -*-
def fibs(n):
result = [0,1]
for i in range(n-2):
result.append(result[-2] + result[-1])
return result
if __name__ == "__main__":
lst = fibs(4)
print(lst)

== Python set() 函数==
set() 函数创建一个无序不重复元素集，可进行关系测试，删除重复数据，还可以计算交集、差集、并集等

add() 方法用于给集合添加元素，如果添加的元素在集合中已存在，则不执行任何操作
