Still getting used to the callback. Very curious if there is any reason/argument for why the callback is not designed to have an explicit function used for the input.
Seems very odd to me that it just calls a function. No idea what would happen if we have multiple functions.

[@Plotly]

yes, a callback is actually a function. It can be seen as a callback decorator and a callback function. Not completely sure about the full design under the hood for the callback.

@@Plotly would be cool if the creator of Dash would comment on/explain why the isn't an explicit naming of the custom function.
I'll play around with it and see if it always calls the first function defined after the callback when several custom functions are defined.

⁠@@utica2burnIt’s the syntax of a decorator. If you know about decorators in Python, they modify the function they decorate. The plotly documentation on their site gives great examples for more complex callbacks, whether nested callbacks, or multiple inputs/outputs.

minimal apps don´t run for me... I try the changing of the debug mode on (running from vscode or spyder) and does not work... docs are not solving nor forums..................

[@Plotly]

Hi Maria, we're sorry you're facing challenges. Can you please clarify what you mean by "minimal apps don´t run for me.".

[@typeer]

How do you solve a problem like Maria

[@rekhaj-ro7un]

Dash is built on the lines of MATLAB
