So I completed the challenge by just typing into the code to delete the exact items I wanted deleted, but I wasn't able to do it in a loop. I would appreciate some clarity and possibly the code to further understand. For those who don't know the challenge it is taking everything out of the list except the numbers in the first list. messy_list = ["a", 2, 3, 1, False, [1, 2, 3]]. Thank you in advanced for the help

There are many approaches to take here, but the one that I took to pass this challenge was the following:

  • Create a new empty list (outside of the loop that you will need)
  • Loop over the elements in the messy_list
  • Check to see if each element is an integer or not, we can do this using type()
  • If it is an integer, then append it to the new empty list
  • After the loop, we can assign messy_list to the new list (so that the challenge will pass successfully)
