The slider function adds an interactive slider to your app, enabling users to input numerical values within a specified range. This is especially useful for dynamic controls, such as selecting a range or adjusting parameters.

​
Parameters

  • label (str): The label displayed next to the slider, indicating its purpose.
  • min_val (float): The minimum value the slider can take.

    max_val=100,
    step=10,
    default=20
)

# Use the selected value
print(f"Slider selected value: {value}")
