简介

Python是数据科学人工智能的交互语言 :)

At Google, python is one of the 3 "official languages" alongside with C++ and Java. Python at Google, Google Group, code.google.com 等服务基于 Python 构建。

Unladen Swallow: A faster implementation of Python, Google发起的项目, 值得关注

将 Python 带入企业级应用: Enterprise Python

版本

主要分支:2.7、3.4、3.5、3.6、3.7


指南

$ python3 -m sysconfig // 返回非常多的配置信息

Python 2.4.4 (#1, Feb  3 2007, 09:56:56) 
[GCC 3.3.5 (Debian 1:3.3.5-13)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> 'Ruby' > 'Python'
True
>>> 'Ruby' > 'Java'
True
>>> 'Ruby' > 'C/C++'
True

有点意思 :)

安装 pip3,如 Debian 环境

$ sudo apt update
$ sudo apt install python3-pip
$ pip3 --version

解释器

函数式编程

通过lambda关键字,可以创建很小的匿名函数。

>>> def make_incrementor(n):
...     return lambda x: x + n
... 
>>> f = make_incrementor(42)
>>> f(0)
42
>>> f(1)
43
