Challenge Task 2 of 2 Create a variable called item3 and assign to it the third element in my_tuple.

Hey Good morning everyone,

I am looking for some assistance on how to add the variable item3 that I created to the third element. I tried .add but I am still receiving errors.

my_tuple = 'I', 'love', 'python' item3 = ['3']

creating_tuples.py
my_tuple = 'I', 'love', 'python'
item3 = ['3']

The question is not asking you to literally add item3 to the existing tuple, but rather to create a new variable (item3) from the existing 3rd element from my_tuple.

At first I was confused because we know tuples are immutable, and don't allow for object assignment after they have been created.

Eventually I could see it was only asking for us to pick out the 3rd element of my_tuple, which is my_tuple[2] and create a new variable from it. Therefore the code looks like this:

my_tuple = ('I', 'love', 'python')
item3 = my_tuple[2]

Thanks it ran!!! I think my issue was as you stated, I was trying to actually add item3 to the existing tuple.

When indexing, the name of the item ("my_tuple" in this case) must come before the brackets.

Also, a numeric value should never be enclosed in quotes. That creates a string instead of a number.

Finally, index values start at 0, so you should always reduce the index by 1. The index for the third item will be 2.

Thank you! This helped out. I was able to run it and cleared the question.
