发帖数: 10 | 1 本人大部分的工作经验在Java。最近面试一个senior python developer (backend)的
职位。
自学python有3,4个月了。刷题也是用的python。但还是缺少自信。请问各位大牛招
python dev 的时候，都问些什么题目？特别是用来考验对python知识深度的问题有哪
些？
谢谢 | c******M
发帖数: 10 | 2 没有人关注么？我自己顶一下。
我觉得python最难学的就是那个什么 co-routine。gevent library用法很hacky。还不
是对所有的library都有用。
欢迎大家拍砖。 | L***s

threading models, GIL, asyncio & alternative async libs like gevent/twisted

writing 2/3 compatible Python code
(for web developers) familiar with django, flask, twisted or tornado
implementation of dict, OrderedDict, deque, etc. in CPython & implications
memory management & fragmentation prevention in CPython
PVM internals and optimization, opcodes and AST hacking
alternative implementations like PyPy & their JIT models
As a "senior python developer", who presumably has spent at least 5000+
hours in this language, you'd better have read through CPython source
code, or even implemented a mini-python interpreter from ground up.

发帖数: 10 | 7 这个话题可大可小。我怕乱说会被大牛喷的。
还是忍不住乱说一把：
其实纯语言角度来说，我还是喜欢Java的。语法规则比较简单。Python的规则太乱，P2
和P3居然不兼容。。。@！#@%#￥
Python的好处就是写程序快。更接近shell script。即写即调试。貌似很多Startup都
倾向于Python，甚至JS。这些公司的生命周期都比较短。至于什么测试，维护。。。等
IPO以后，交给Java程序员打理吧。

发帖数: 10 | 9 多谢Shelley MM。 建议先记下了。暂时不打算往data scientist方面发展。这个职位
是做 Infrastructure方面的。
