Python : How to write a function in python

Due some circumtance , I had opted to use python script..

Well, for python script , you need to be extra careful with the white space
and tab..

this is an example of using python function to ease the work.

it might not be beautiful or simplified enough .. but enough to drive me nut
looking for the white space.

tips : do not combine usage of “tab” and “space” inside one python script… be consistent.
if using tab.. use tab till the end..
if using space.. use space all the time.
else it will drive you nut before you can nail where is the missing space.. 🙂

# example usage : 
print "translating 'No rain' = " + getBM("No rain")

then to test it..
