Kamen got the book Python für Kids. To enable him to use the book on OS X, I wanted to setup the Python environment on the Mac as on the PC: Install IDLE and, to hide the differences between integer and floating point math, configure to use the new division.
Installing IDLE on OS X 10.3 is easy with MacPython. IDLE comes as bundle, ready to be launched with the mouse from the Finder. But for using the new division without the need for from __future__ import division, IDLE must be started with options. How to embed these options in the IDLE.app bundle?
With the help of Jack Jansen and Andreas Glenn from the pythonmac-sig, I found out how:
- Use the Finder to make a backup copy of
/Applications/MacPython-2.3/IDLE, just in case you get
- Open /Applications/MacPython-2.3/IDLE.app/Contents/MacOS/IDLE
in your favourite editor
- Insert two lines after the first sys.argv.insert line. It
should look like this:
sys.argv.insert(1, mainprogram) sys.argv.insert(1, "-Qnew") sys.argv.append("-n")
That’s it! You can launch IDLE from the Finder and verify that 5/2 equals 2.5 😉
