Introduction to Python

ChallengeChallenge

Task

You've been provided with a people list that includes sub-lists of individuals' names and their heights in centimeters. Drawing from the approach in the last chapter (iterating through the main list), you should convert each person's height from centimeters to inches by dividing by 2.54. Then, round that number to 2 decimal places and store it in the ht_in variable within the loop on [line 8].

Everything was clear?
