U-nderstand

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

• Can the list be empty?
  • Yes. In that case, your function should return an empty list.

P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Create a function that multiplies every element in a list by a given number.

1) Create and initialize an empty list to hold the result 
2) For each element in the list
  a) multiply the element by the multiplier
  b) add the new value to the result list
3) Return the result list

def multiply_list(lst, multiplier):
	result = []
	for num in lst:
		result.append(num * multiplier)
	return result
