python shell

Python是一个非常实用、流行的解释型编程语言,其优势之一就是可以借助其交互的shell进行探索式地编程。你可以试着输入一些代码,然后马上获得解释器的反馈,而不必专门写一个脚本。但是Python自带的shell也有一些局限性,例如无法自动补全、不能高亮语法等。

好在强大的Python对默认shell进行了扩展,开发了许多漂亮的Python shell。每一个都提供了一个极好的交互性的Python 体验。今天我就为大家介绍其中较为优秀的一款 — bpython。

bpython简介

bpython是一个不错的Python解释器的界面,开发者的目的是提供给用户所有的内置功能,很像现在的IDE(集成开发环境),但是将这些功能封装在在一个简单,轻量级的包里,可以在终端窗口里面运行。

bpython并不追求创造任何新的或者开创性的东西。相反,它聚集了一些简洁的理念,关注于实用性和操作性。

如何安装

bpython最新版本是0.15。有四种安装方式:

  • 官网下载最新版本的tarball:http://bpython-interpreter.org/releases/
  • 克隆bpython的Git仓库:git clone https://github.com/bpython/bpython/
  • 通过pip安装:pip install bpython
  • 通过系统自带的包管理器:apt-get install bpython

想让bpython正常运行的话,还需要安装以下依赖包:

Pygments requests curtsies >= 0.1.18,

具体功能

功能十分丰富,具体包括:

  • 内置的语法高亮 – 使用Pygments排版你敲出的代码,并合理配色
  • 根据你的行为,显示自动补全的建议
  • 为任何Python函数列出所期望的参数 – 可以显示你调用的任何函数的参数列表
  • “Rewind”功能会调出内存里的最后一行代码并重新执行
  • 可以将你输入的代码送到pastebin
  • 可以将你输入的代码保存到一个文件
  • 自动缩进
  • 支持Python 3

类似的Python shell

除了bpython之外,还有IPython、ptpython和dreampie等三个类似的Python shell。

知道什么是bpython,它的安装方法,功能了吧,希望大家可以深入的进行了解。
