itertools 模块 该模块包含了一系列处理可迭代对象(sequence-like)的函数,从此迭代更任性。 迭代器有一些特点,比如lazy,也就是只有用到的时候才读入到内存里,这样更快更省内存;比如只能调用一次,会被消耗掉。 import itertools as itls 合并迭代器: chain()与izip() chain()函数接收n个可迭代对象,然后返回一个他...

I enjoyed the VM-like puzzles the most, after that the parser ones,3 and after that the ones that could be solved with interesting uses of iterators and Itertools. The cryptography puzzles like today’s, I didn’t enjoy that much. I appreciated that there were so many Game of Life varia...
