This was my solution

# I want to make it clear I will be using very little python verbage to explain this in plain english.

students_period_A = ["Alex", "Briana", "Cheri", "Daniele"]
students_period_B = ["Dora", "Minerva", "Alexa", "Obie"]

for student in students_period_A:
  # student is the temporary variable.  This is what we are going to call in each list.
  # You want to put A into B.  So "A" is going to be the focus for the statement.
  # So now, each students_period_A is now counted as "students".  So you want to........ 
  # If you print it you should see only four people, as it is only wanting to print the students, not the variable

In your comment “# You want to put A into B.” and then at the last comment it says “If you print it you should see only four people,…” then what is the point of even writing “--------.append()” code? if you can not add elements of B in A. It was not clear for me to understand the purpose of -----------.append()'s existence.

Yes. I discovered .append() while trying to solve this exercise as well! :slight_smile:
