The instructions are: Create a variable named y_words that uses a list comprehension to only contain the words from words that start with the letter "y".

It doesn't look like you've started yet, but some things you know need doing:

  • you need a variable name "y_words"
  • the variable will be assigned from a list comprehension
  • list comprehensions have brackets around them
  • part of a list comprehension will be similar to a loop
  • another part will be a conditional test
  • the condition needs to check the first letter of each word

Give it a try and if you still have trouble, show your code so far.

Hi, you can check the first item on each string if it equals to 'y'

y_words = [word for word in words if word[0]=='y']
