python - How to calculate the sum of numbers divisible by 3 and 5 using lambda's range, map, filter and reduce -

i need calculating sum of numbers divisible 3 or 5 within given range. far i've gotten this;

print filter(reduce(map(lambda x, y: x % 3 == 0 or y % 5 == 0, x + y, range(30)))) 

which throws error

traceback (most recent call last): file "<pyshell#65>", line 1, in <module> print filter(reduce(map(lambda x, y: x % 3 == 0 or y % 5 == 0, x + y, range(30)))) nameerror: name 'x' not defined 

i don't think i'm close finding solution or on right track, if point me in direction great, cheers.

after defining a , b b > a:

reduce(lambda x, y: x + y, filter(lambda x: x % 3 == 0 or x % 5 == 0, range(a, b))) 

in case:

reduce(lambda x, y: x + y, filter(lambda x: x % 3 == 0 or x % 5 == 0, range(30))) 

or without reduce , filter:

sum(x x in range(30) if x % 3 == 0 or x % 5 == 0) 

if range of values large (not 30) use xrange if on python 2 returns generator instead of list.

if want include map function can use identity function follows:

reduce(lambda x, y: x + y, filter(lambda x: x % 3 == 0 or x % 5 == 0,                                   map(lambda x: x, range(30))))
