You need to make the second element a 1-tuple, eg:

The point here is: List is a mutable sequence type. So you can change a given list by adding or removing elements. Tuple is an immutable sequence type. You can't change a tuple. So you have to create a new one.

If the comma bugs you, you can specify it's a tuple using

2 How do you add items to a tuple in Python?Use the + operator to add an element to a tuple. a_tuple = ("element1", "element2"). print(a_tuple) Output. ('element1', 'element2'). new_element = ("element3",). a_tuple = a_tuple + new_element.. print(a_tuple) Output. ('element1', 'element2', 'element3'). Can you append values to a tuple?Much like strings, tuple values can be altered or appended by simply concatenating a new value onto the existing one. It combines two different sets of tuples into one and doesn't actually change existing values, maintaining the immutability of the data type.
Is tuple editable in Python?Once a tuple is created, you cannot change its values. Tuples are unchangeable, or immutable as it also is called.
Can we update items in tuple?Tuples are unchangeable, meaning that you cannot change, add, or remove items once the tuple is created.
