大家好，我是老表～
本文旨在讲解如何在Android平板或手机上搭建Python开发环境，帮助Python初学者有效利用碎片化时间进行学习，从而达到良好的学习效果。

一、Termux安装与配置

1. 系统要求

• Android 7.0以上的平板或手机。这里建议使用兼顾了便携性和屏幕尺寸的8寸平板。
• 2G以上可用空间。由于需要安装各种软件包，对存储空间的消耗还是比较大的。
  
  

2. Termux安装

Termux 是一款支持 Linux 环境的 Android 终端模拟器APP。你无需对手机进行root或额外设置即可使用。这款APP会在手机中自动安装一个最小化基本系统，并支持使用 APT 包管理工具安装软件。

• 主程序Termux下载地址：

https://f-droid.org/repo/com.termux_106.apk

• 美化工具Termux:Styling下载地址：

https://f-droid.org/repo/com.termux.styling_29.apk

3. Termux基本操作

• 快捷键

Ctrl + A -> 将光标移动到行首
Ctrl + E -> 将光标移动到行尾
Ctrl + C -> 中止当前进程
Ctrl + D -> 注销终端会话
Ctrl + K -> 从光标删除到行尾
Ctrl + U -> 从光标删除到行首
Ctrl + L -> 清除终端
Ctrl + Z -> 挂起（发送SIGTSTP到）当前进程

音量加 + E -> Esc键
音量加 + T -> Tab键
音量加 + 1 -> F1（音量增加 + 2 → F2…以此类推）
音量加 + 0 -> F10
音量加 + B -> Alt + B，使用readline时返回一个单词
音量加 + F -> Alt + F，使用readline时转发一个单词
音量加 + X -> Alt+X
音量加 + W -> 向上箭头键
音量加 + A -> 向左箭头键
音量加 + S -> 向下箭头键
音量加 + D -> 向右箭头键
音量加 + L -> | （管道字符）
音量加 + H -> 〜（波浪号字符）
音量加 + U -> _ (下划线字符)
音量加 + P -> 上一页
音量加 + N -> 下一页
音量加 + . -> Ctrl + \（SIGQUIT）
音量加 + V -> 显示音量控制
音量加 + Q -> 切换显示的功能键视
音量加 + K -> 切换显示的功能键视图

4. 修改软件源

sed -i 's@^\(deb.*stable main\)$@#\1\ndeb https://mirrors.tuna.tsinghua.edu.cn/termux/termux-packages-24 stable main@' $PREFIX/etc/apt/sources.list
sed -i 's@^\(deb.*games stable\)$@#\1\ndeb https://mirrors.tuna.tsinghua.edu.cn/termux/game-packages-24 games stable@' $PREFIX/etc/apt/sources.list.d/game.list
sed -i 's@^\(deb.*science stable\)$@#\1\ndeb https://mirrors.tuna.tsinghua.edu.cn/termux/science-packages-24 science stable@' $PREFIX/etc/apt/sources.list.d/science.list
apt update && apt upgrade

5. 安装基本组件

plugins=(
    git
    python
    colorize
    zsh-interactive-cd
    zsh-navigation-tools

}

• 配置vim-which-key

" 将空格设置为whichkeyleader键
nnoremap <silent> <leader> :WhichKey '<Space>'<CR>

" whichkey基本配置
let g:which_key_timeout = 100
let g:which_key_display_names = {'<CR>': '↵', '<TAB>': '⇆'}
let g:which_key_map =  {}
let g:which_key_sep = '→'
let g:which_key_use_floating_win = 0
let g:which_key_max_size = 0

" 呼出whichkey时隐藏状态栏
autocmd! FileType which_key
autocmd  FileType which_key set laststatus=0 noshowmode noruler
  \| autocmd BufLeave <buffer> set laststatus=2 noshowmode ruler

" 自定义whichkey
let g:which_key_map['?'] = 'search word'
let g:which_key_map['/'] = [ ':call Comment()'                                 , 'comment' ]
let g:which_key_map['.'] = [ ':e $MYVIMRC'                                     , 'open init' ]
let g:which_key_map[';'] = [ ':Commands'                                       , 'commands' ]
let g:which_key_map['e'] = [ ':CocCommand explorer --toggle --sources=file+'   , 'explorer' ]
let g:which_key_map['n'] = [ ':let @/ = ""'                                    , 'no highlight' ]
let g:which_key_map['q'] = [ '<Plug>(coc-fix-current)'                         , 'quickfix' ]
let g:which_key_map['u'] = [ ':UndotreeToggle'                                 , 'undo tree']
let g:which_key_map['t'] = [':FloatermNew --wintype=normal --height=6'        , 'terminal']
let g:which_key_map['r'] = [ ':FloatermNew ranger'                            , 'ranger']

call which_key#register('<Space>', "g:which_key_map")

• 在NeoVim中运行Python脚本

"在普通模式下，按r来运行Python脚本
noremap r :call RunPython()<CR> 
func! RunPython()
    exec "w"
    if &filetype == 'python'
        exec "!time python %"
    endif
endfunc
