Hi Eri,



Ah!  Check the 'break' statements in the main loop of the program:

>              proceed()
>          except ValueError:

>          break

>              print "temp in F is: ", f2c(getctemp)

The breaks cause us to jump out of the while loop if either temperature
choice gets selected.


I'm guessing that you're using a C switch statement idiom.  But since that
idiom isn't applicable in Python, you should just drop them.


Good luck to you!
