python中的list,list comprehension,tuple, zip等等是不是从haskell学过来的?
回复内容:
不是!首先Python的list和Haskell的list是两回事啊。。后者是链表,前者是动态数组。。
然后Haskell的list comprehension的实现依靠的是转成map/filter(不考虑fusion优化),最后通过递归来实现;Python的list comprehension的实现依靠的是__iter__方法(也就是迭代器的意思),最后通过循环来实现,而迭代器的终止还需要catch一个异常。。 我跟你说,他们都是从lisp学来的!!!
“lisp是所有语言的鼻祖,包括出现比他早的。”
(逃 这些不都是正常人拍拍脑袋就能想到的东西嘛……就像中缀表达式、数组、浮点数,谁需要学呢?
