Python 3.x 如何使绘图划线日期选择器范围和按钮工作

我正在使用

Dash

by

Plotly

创建一个仪表板，但它将日期范围作为输入。但我在尝试模仿中所示的简单示例时，遇到了

TypeError

。我不明白我做错了什么。下面是我的代码：

import dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output, State
from datetime import datetime as dt

app = dash.Dash(__name__)

app.config['suppress_callback_exceptions'] = True
app.css.config.serve_locally = True
app.scripts.config.serve_locally = True

app.layout = html.Div(children=[

    html.H1(children='AE Analytics Dashboard', style={'color': 'gray', 'text-align': 'center'}),
    html.Div(
        html.Div(
            dcc.Input(id='input-box', placeholder='Enter AE Name', type='text',value=''),
            dcc.DatePickerRange(
                id='date-picker-range',
                start_date_placeholder_text= 'Select a date!',
                end_date_placeholder_text='Select a date!'
            )
        ),
        html.Button('Submit', id='button'),
        # html.Div(id='output-container-button', children='Enter a value and press submit')
    )
])

if __name__ == "__main__":
    app.run_server(debug=True)

错误：

TypeError:不可损坏的类型：“DatePickerage”

尝试使用

html.Button

时出现以下错误：

类型错误：不支持的格式字符串传递到按钮。格式

我解决了。这是一个愚蠢的错误。下面是更正后的代码，供任何人参考

import dash
import dash_core_components as dcc
import dash_html_components as html
from dash.dependencies import Input, Output, State
from datetime import datetime as dt

app = dash.Dash(__name__)

app.config['suppress_callback_exceptions'] = True
app.css.config.serve_locally = True
app.scripts.config.serve_locally = True
app.layout = html.Div(children=[

    html.H1(children='AE Analytics Dashboard', style={'color': 'gray', 'text-align': 'center'}),
    html.Div(
        html.Div([
            dcc.Input(id='input-1-state', type='text', placeholder='AE Name', style={'text-align': 'center'}, value=''),
            dcc.DatePickerRange(
            id='date-picker-range',
            start_date_placeholder_text= 'Select a date!',
            end_date_placeholder_text='Select a date!'
        ),
            html.Button(id='submit-button', n_clicks=0, children='Submit')
            ]),
        ),
])

if __name__ == "__main__":
     app.run_server(debug=True)

你能解释一下吗？我遇到了类似的错误，我无法理解仅仅是看你的代码。无论你想在一个特定的

Div

中使用什么组件，你都必须将它们像列表一样包装在一个iterable中。比较问题和答案之间的

html.Div

下面的

html.H1

，让我知道你是否能找出差异。你能解释一下吗？我遇到了类似的错误，我无法理解仅仅是看你的代码。无论你想在一个特定的
