3.1 Asking user for input

To ask the user for input, we can use the built-in input function:

viewof input_1 = Inputs.text({label: "User's input:", value: "Jan", submit: "Update"})

Run the code in the cell above several times and enter different names.

Note that the input function always returns a string (even if the user enters a number), but we can use type conversion functions such as int and float to convert the given string to other types:

viewof input_2 = Inputs.text({label: "User's input:", value: "2000", submit: "Update"})

If the user enters something else than (just) an integer, the conversion will fail with a ValueError. Try it!
