What is the fastest python code to get the index of a huge
list of incrementing interval numbers, given a number?

ie:

>ic = [0,10,30,60,90,100,800,1000]
>print pyfuncsomething(ic,50)
2
>print pyfuncsomething(ic,500)
5

the slower code is like this:

def pyfuncsomething(ic,n):
     for i,el in enumerate(ic):
         if n > el:
                return i
     raise Exception, 'Not found'
thx
