Challenge Question Solution
Even though there is a specific answer we’re looking for, this was a bit of a trick question.
If your first action was turning around and asking, “what is the problem?” or “why am I evacuating the city?”, then you answered correctly. The reason we need to ask this question first is because different problems require different solutions. If you began writing an evacuation plan that required using cars, what if the problem was that all the streets were flooded. It wouldn’t be very wise to advise people to drive out of the city. Sometimes the answer to a question is a question itself. One other lesson to take away from this is that you should always take a step back and think through each problem.
Never assume you know the solution right away; it’s okay to ask questions.
ChApter 4 LIsts And Loops
Weekly Challenges
To test out your skills, try these challenges:

1. 
   Pyramids: Use a for loop to build a pyramid of x’s. It should be modular so that if you loop to 5 or 50, it still creates evenly spaced rows. Hint: Multiply the string “x” by the row. For example, if you loop to the range of 4, it should produce the following result:
   

>>> x
>>> x x
>>> x x x

2. 
   Output Names: Write a loop that will iterate over a list of items and only output items which have letters inside of a string. Take the following list, for example, only “John” and “Amanda” should be output:
   

>>> names = ['John', ' ', 'Amanda', 5]

3. 
   Convert Celsius: Given a list of temperatures that are in Celsius, write a loop that iterates over the list and outputs the temperature converted into Fahrenheit. Hint: The conversion is “F = (9/5) ∗ C + 32”:
   

>>> temps = [32, 12, 44, 29]
Output would be [89.6, 53.6, 111.2, 84.2]
