无法修复vscode中的错误："(“未关闭”)。
提问于 2022-03-26 08:30:20
我一直试图用巧妙的破折号进行可视化，并希望尝试第一个应用程序的例子，从网站文档。我复制并粘贴了大部分代码，并确保了正确的缩进，但似乎始终在括号中出现错误。有什么建议吗？
import dash
import dash_core_components as dcc
import dash_html_components as html
external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']
app = dash.Dash(__name__, external_stylesheets=external_stylesheets)
app.layout = html.Div(children=[
html.H1(children='Hello Dash'),
html.Div(children='''
Dash: A web application framework for Python.
'''),
dcc.Graph(
id='example-graph',
figure={
'data': [
{'x': [1, 2, 3], 'y': [4, 1, 2], 'type': 'bar', 'name':
{'x': [1, 2, 3], 'y': [2, 4, 5], 'type': 'bar', 'name':
],
'layout': {
'title': 'Dash Data Visualization'
}
}
)
])
if __name__ == '__main__':

我已就括号没有关闭的地方发表意见。另外，您还缺少了"name"的值。我也对此发表了意见。P指括号()，C指圆括号{}，S指方括号[]。
