Python的for迴圈其實可以搭配else使用, 其實應該稱作no-break. 與for使用的else表示如果for迴圈被完整執行, 那就執行else的部份. 如果迴圈被中斷了(break), 那else的部份也不會被執行. 所以上述的程式可以改寫成: def find(seq, target): for i, value in enumerate(seq): if value == target: break else...
. On the other hand: sort of everything in programming is a kind of trade off, it's the land of trade offs. Maybe the LUA programming language has a less annoying syntax, but it's not used as widely as python, and it comes with less libraries, meaning that not all 'batteries are...
