Here's a simple list:

cats = ['Maine Coon', 'Tabby', 'Siamese', 'Garfield', 'Sylvester']

cats

['Maine Coon', 'Tabby', 'Siamese', 'Garfield', 'Sylvester']

Iterate through the list and print each cat.

# Your code here

Create a new list cat_jrs by appending ‘Jr.’ to each of the cats names.

# Your code here

Sort the list in alphabetical order.

# Your code here

Sort the list in reverse alphabetical order

# Your code here

Look up a new string or list method and explain how it works.

# Your code here

Extension: Sort the list by the 3rd letter of each name.

Hint: look at the docstring's optional parameter, key=.
You can then define a special function called a lambda function on the fly like this:
lambda thing: thing*-1 or lambda x: operation(x)

Like a for loop you can create any variable name after calling lambda.
After calling lambda and a variable name, you then always use a colon :.
To the right of the colon is whatever you want your function to do with your variable.

More completely:

numbers = [5,3,7,82, 17]
numbers.sort()
numbers

[3, 5, 7, 17, 82]

numbers.sort(key=lambda x: x*-1) #Effectively sorts in descending order by taking the inverse
numbers

[82, 17, 7, 5, 3]

numbers.sort(key=lambda num: abs(11-num)) #Try to explain what this does.
numbers

[7, 17, 5, 3, 82]
