AutomateTheBoringStuff.Ch15.Projects.P1_prettifiedStopwatch module

Prettified stopwatch

Expand P3_stopwatch from this chapter so that it uses str.rjust() and str.ljust() string methods to “prettify” the output.

Instead of output such as this:

Lap #1: 3.56 (3.56)
Lap #2: 8.63 (5.07)
Lap #3: 17.68 (9.05)
Lap #4: 19.11 (1.43)

… the output will look like this:

Lap # 1:  3.56 (  3.56)
Lap # 2:  8.63 (  5.07)
Lap # 3: 17.68 (  9.05)
Lap # 4: 19.11 (  1.43)

Next, use pyperclip to copy the text output to the clipboard so the user can quickly paste the output to a text file or email.

AutomateTheBoringStuff.Ch15.Projects.P2_scheduledComicDownloader module

Scheduled comic downloader

Write a program that checks the websites of several web comics and automatically downloads the images if the comic was updated since the program’s last visit.

Your operating system’s scheduler (Scheduled Tasks on Windows, launchd on OS X, and cron on Linux) can run your Python program once a day.

The Python program itself can download the comic and then copy it to your desktop so that it is easy to find. This will free you from having to check the website yourself to see whether it has updated.

Note

This only downloads from http://www.lefthandedtoons.com/ and http://buttersafe.com/ because all websites are different.
