Unit 1 Session 1 (Click for link to problem statements)

Understand what the interviewer is asking for by using test cases and questions about the problem.

• Do I need to modify the provided function?
  • No.

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Create a function to safely get the first element of a list.

1) Create a new function with a parameter for the list 2) If the list is not empty, return the first item 3) Otherwise, return None

def get_first(lst): if lst: return lst[0] return None
