The new tabs in Safari 4 are nice, but I prefer the old classic look. If you’re like me, like I know I am, use these commands in the terminal to disable the new look:
defaults write com.apple.Safari DebugSafari4TabBarIsOnTop -bool NO
defaults write com.apple.Safari DebugSafari4IncludeToolbarRedesign -bool NO
defaults write com.apple.Safari DebugSafari4LoadProgressStyle -bool NO“A generator and a list used like a cache.”

>>> range(20)[::2]
[0, 2, 4, 6, 8, 10, 12, 14, 16, 18]
This can be used to access every third element by using ::3 and so on.
To reverse a list, use the extended slice with an argument of -1.
>>> range(8)[::-1]
[7, 6, 5, 4, 3, 2, 1, 0]
