My first AppleScript

I read the book two months ago, but I never wrote a line of AppleScript. But now I did!

-- Open the terminal application and two windows
-- the right window shall be a python shell and shall
-- have the full height and be at the right edge of the screen
-- the first window stays at the left side of the screen
-- in normal size
tell application "Terminal"
  activate

-- this is cruel, there is no "make new window" I have
-- to step through the menu
-- yucky ... but it works .... jippi
-- thanks to to Fork on #ignmac and to
-- http://bbs.applescript.net/viewtopic.php?pid=32691
tell application "System Events"
   click menu item "Neues Shell-Fenster" of menu "Ablage"\
   of menu bar item "Ablage" of menu bar 1 of process "Terminal"
end tell

tell window 1
set position to {0, 0}
end tell

-- get the width+height of the screen

try
  set window_info to do shell script\
  "defaults read com.apple.loginwindow\
  | grep -w 'NSWindow Frame About This Mac'"
  set screen_width to (word 13 of window_info as number)
  set screen_height to (word 14 of window_info as number)
on error -- use defaults on failure
  set screen_width to 1024
  set screen_height to 768
end try

-- set window 2 dims
tell window 2
  set position to {screen_width - 1000, 0}
  set size to {1000, screen_height}
end tell

-- open the python shell in window 2
do script "clear; python" in window 2

end tell
