Indexes and values (1)

Using a for loop to iterate over a list only gives you access to every list element in each run, one after the other. If you also want to access the index information, so where the list element you're iterating over is located, you can use enumerate().

As an example, have a look at how the for loop from the video was converted:

fam = [1.73, 1.68, 1.71, 1.89]
for index, height in enumerate(fam) :
    print("person " + str(index) + ": " + str(height))

Exercise instructions

  • Adapt the for loop in the sample code to use enumerate() and use two iterator variables.
  • Update the print() statement so that on each run, a line of the form "room x: y" should be printed, where x is the index of the list element and y is the actual list element, i.e. the area. Make sure to print out this exact string, with the correct spacing.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# areas list
areas = [11.25, 18.0, 20.0, 10.75, 9.50]

# Change for loop to use enumerate() and update print()
for a in areas :
    print(a)
