Responsive is better than fast

Great! That's the first line. Now, how would we print the last line?

You'll want to edit [0] to include the index of the last value in the array. You can check out quotes.txt to see the number of lines.

Since the first value is the zeroth, you'll need to remove one from the number you include for the last value.

Comment with the last quote

Run your code and copy the value to your clipboard.

Paste the quote as a comment here and I'll follow up with next steps!

Now that you're familiar with arrays, it's time to find a random line.

Generate a random number

Rather than [0] or [13] for our array value, we want the number to be chosen at random. Of course, it can't be any number. It should be a whole number between 0 and 13.

To generate random numbers, we'll use a Python module, a built-in extension of the language.

At the very top of your get-quote.py file (above the def line), add this line:
import random

Now find where you print out one value from the array. Before that line, add the following:

  last = 13
  rnd = random.randint(0, last)

The last variable holds the highest index for the array. Then our random number is stored in rnd using the random.randint function, which takes the lowest-possible number (zero) and the highest-possible number (stored in last).

Note If you want to add or remove quotes from your text file, you could change the last variable to update automatically:
last = len(quotes) - 1

Finally, update the line where we print a single quote. Instead of including a number between the brackets, we'll put our random number variable:
print(quotes[rnd])

Try running your code a few times and your quotes should now be chosen at random.

Push your changes

It's been awhile since we've saved our code in the repo. Take the oppportunity now:

• git add get-quote.py
• git commit -m "Random quote bot is working"
• git push

When I see the push come through, I'll comment here!

You have a working random quote bot! You've finished this course, but the learning never stops. I've created one last issue for you to explore Python on your own.
