Not sure how to create a variable called item3.

what's the value of item3? Tuple is immutable.

create_tuple.py
# insert your code here
my_tuple = 'I', 'love', 'python'

my_tuple = list(my_tuple)
my_tuple[2] =  'item3'
my_tuple = tuple(my_tuple)

Hey Lening Li, your first line is correct for Task 1. Items separated by comma form a tuple. Some coders wrap the items in parens to visually mark the tuple, but this is unnecessary as the commas make the tuple not the parens.

For Task 2, β€œitem3” is a label so it goes on the left side of the =. On the right side goes the definition. Tuples can be referenced using indexing in the same manner as lists, so the third item can be referenced using [2]. More it is zero-based numbering: 0, 1, 2, etc. making 2 the third item.

Your second to last line of code above would be correct if the sides were switched around the equals sign. Since you’re defining a new variable and not a string, the quotation marks are not needed around item3.

Post back if you need more help. Good luck!!
