how can I do this?

[Eric Yohanson]

I would like to know if it is possible in python 2.21 to make a text
entry widget that initially show nothing but when the user type the
first character displays a template like "00#00:01+2" for the previous
I have only enter the numbers 1 & 2. the numbers would need to enter
from right and travel to the left as more are entered replacing the
"0" place holders.  How difficult would this be to do and what should
my approach be to this.  Any help wuld be great.
