4.0.4 Do Now

1. Log in to REPL

2. Look at the following code:

# my_building is a representation of the apartments on each floor of my 3 story building
my_building = [
  ['apt1a', 'apt1b', 'apt1c'],  
  ['apt2a', 'apt2b', 'apt2c'],
  ['apt3a', 'apt3b', 'apt3c']
]
print("first floor: " + str(my_building[0]))
print("first floor, 3rd apartment: " + my_building[0][2])

Answer the following questions on a piece of paper:

• What would the print functions print?
• Why does the first print function need the str function in str(my_building[0]), but the second print function does not need str for my_building[0][2]?
• How you would access the 2nd apartment of the 3rd floor (apt3b)?
