python - Mapping a range of integers to a single integer -

i have function receives integer input , depending on range input lies in, assigns difficulty value. know can done using if else loops. wondering whether there more efficient/cleaner way it.

i tried this

time_rating_key ={ range(0,46):1, range(46,91):2, range(91,136):3, range(136,201):4, range(201,10800):5, }

but found out can utilize range key in dict(right?). there improve way this?

the simplest way write short function:

def convert(n, difficulties=[0, 46, 91, 136, 201]): if n < difficulties[0]: raise valueerror difficulty, end in enumerate(difficulties): if n < end: homecoming difficulty else: homecoming len(difficulties)

examples:

>>> convert(32) 1 >>> convert(68) 2 >>> convert(150) 4 >>> convert(250) 5

as side note: can utilize range dictionary key in python 3.x, not straight in 2.x (because range returns list). do:

time_rating_key = {tuple(range(0, 46)): 1, ...}

however won't much help!
