Dash Xinet 与 Sanstyle#
为了方便管理代码和数据创建仓库：
xinetzone/dash-xinet：简化 Dash 的使用。
SanstyleLab/plotly-dastsets：存储一些数据集以及展示图片。
xinetzone/sanstyle：处理一些常见任务。
安装：
pip install dash-xinet sanstyle
统一载入模块和库（后文将省略这部分代码）：
from dash_xinet.server import create_app, run_server
from dash_xinet.utils.nav import create_nav
external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']
app = create_app(__name__, external_stylesheets=external_stylesheets)
Dash 应用使用和运行：
layout = ... # 布局
await run_server(app, layout, port=8050) # 启动应用
关于 sanstyle#
可以直接批量修改文件后缀：
from sanstyle.utils import rename_suffix
rename_suffix(root, old, new)
root
: 需要修改的跟目录
old
: 被修改的文件后缀，如 .txt
new
: 修改后的文件后缀，如 .rst
创建 <embed> 元素#
from sanstyle.display.html import Embed
snippet_url = 'https://dash-tests.herokuapp.com'
figure_n_slider_dash = Embed(snippet_url + '/examples/figure-n-slider',
className='w3-pale-blue',
height=500)
figure_n_slider_dash
导入 plotly-dastsets#
import pandas as pd
from sanstyle.github.file import lfs_url
url = lfs_url('SanstyleLab/plotly-dastsets',
'simple/usa-agricultural-exports-2011.csv')
df = pd.read_csv(url)
df.head()
