Does she have a recent Time Machine backup that she can restore from?  Otherwise the solutions are all fairly painful:

1) Install Python 2.7 from scratch (easy).  Then figure out where to put symlinks that point back to the install (mildly annoying/hard).  Note that Python 3 won't work; none of the built-in scripts expect it.

2) OS X recovery - http://www.macworld.co.uk/how-to/mac/how-reinstall-mac-os-x-using-internet-recovery-3593641/ I've never had to do that, so I have no idea how easy/reliable it is.  I **think** its supposed to save all the data on the drive, but again, I've not done this, so I can't make any guarantees.

3) Wipe it clean and reinstall from scratch.

Honestly, I hope she has a time machine backup.  I've had to do recoveries a couple of times, and it can really save you.

Good luck,
Cem Karan
