斐波那契數列，數列前兩項為1，之後每一項都是前兩項之和。

a, b = 0, 1
while b < 100:
print(b)
a, b = b, a + b
預設print輸出結果後會自動換行，如果不希望換行，只做間隔的話，就通過另乙個引數end來替換這個換行符

python 演算法 小試牛刀
1.列印從1到100，碰到3倍數用fizz代替，碰到5倍數，用buzz代替，3和5的倍數，fizzbuzz代替 def func for i in range 1,101 if i 3 0 i 5 0 print fizzbuzz elif i 3 0 print fizz elif i 5 0 p...
boost graph lib 小試牛刀
最近要做社會網路的社群發現，發現用bgl能減少不少 量。經過一番調研發現bgl封裝的很牛叉，dijkstra等演算法統統具備，奈何自己對泛型程式設計不太熟，遇到問題還是很糾結。primer泛型程式設計 演算法部分和stl原始碼分析接下來有時間一定要讀下。下面僅以鄰接鍊錶和自定義節點為例 typede...
