阅读 Python dash 代码的时候有个问题, 那个包的调用有问题?

这个是实例的代码, 后面的代码里面有 import dash_html_components as html

html.Div, html.Table

这些东西, 然后我搜索了一下找到了 dash_html_components 这个文件夹, 但是文件夹是这样的, 没有看到 Table 或者 Div 这样的定义,这个问题是怎么处理的?

import dash import dash_core_components as dcc import dash_html_components as html import pandas as pd df = pd.read_csv( 'https://gist.githubusercontent.com/chriddyp/' 'c78bf172206ce24f77d6363a2d754b59/raw/' 'c353e8ef842413cae56ae3920b8fd78468aa4cb2/' 'usa-agricultural-exports-2011.csv') def generate_table(dataframe, max_rows=10): return html.Table( # Header [html.Tr([html.Th(col) for col in dataframe.columns])] + # Body [html.Tr([ html.Td(dataframe.iloc[i][col]) for col in dataframe.columns ]) for i in range(min(len(dataframe), max_rows))] ) app = dash.Dash() app.layout = html.Div(children=[ html.H4(children='US Agriculture Exports (2011)'), generate_table(df), dcc.Interval( id='interval-component', interval=1*1000, # in milliseconds n_interval=0 ) ]) if __name__ == '__main__': app.run_server(debug=True) 

我看了一下 init.py 的定义, 是不是把那些定义都写到 js 文件里面了。

import os as _os import dash as _dash import sys as _sys fro .version import version

_current_path = _os.path.dirname(_os.path.abspath(file))

_compOnents= _dash.development.component_loader.load_components( _os.path.join(_current_path, 'metadata.json'), 'dash_html_components' )

_this_module = _sys.modules[name]

_js_dist = [{ "relative_package_path": "bundle.js", "external_url": ( "https://unpkg.com/dash-html-components@{}" "/dash_html_components/bundle.js" ).format(version), "namespace": "dash_html_components" }]

for component in _components: setattr(_this_module, component.name, component) setattr(component, '_js_dist', _js_dist)
