how to type a tuple

Question

How do you type the tuple value that has just the integer value 42 in it?

t = (42)

t = (42,) (The trailing comma is mandatory.)

t = (), .insert(42)

t = [42,]

Answer 1

If you want to type the tuple with single value either its integer or any other datatype use round brackets to create a tuple and use comma after the value like

t = (42,)

for type tuple with single value comma is mandatory after the value.

If you don't use comma at the end of integer it will create a integer type variable like

t = (42) when you check its type using type() function it shows integer

t = [42,] create a list containing single integer

t = ().insert(42) throw an error because tuple doesn't have insert method and you cannot

add new value to a tuple because it is immutable (means unchangeable)
