Exercise: Multiple Inputs and Outputs to Callbacks

Exercise 1

Create a Dash app that allows the user to enter a number x as input. Now create two outputs, each of them as separate markdown components.

• The first markdown component should read x² = [squared_num]
• The second markdown component should read x³ = [cubed_num]

Here [squared_num] and [cubed_num] represent the computed values from the callback function calculation.

Solution

• Two lambda functions are defined on line 1 and 2, respectively, for calculating the square and cube of a number, respectively.

• The app layout is set using the dbc.Container method on line 8 which includes:

  • An H1 header element on line 9, displaying Exercise 1.

  • An Input element on line 11 from Dash Core Components, allowing users to input a number.

  • Two Markdown elements on line 12 and 13, respectively, from Dash Core Components with IDs of output1 and output2 to display ...
