listcomprehension, add elements?

[cirfu]

[a+b for a,b in zip(xrange(1,51), xrange(50,0,-1))]

[51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51,
51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51,
51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51, 51]

i want to add all the elemtns a s well. can i do this all in a
listcomprehension?

i can do this ofc:
reduce(lambda x,y:x+y,[a+b for a,b in zip(xrange(1,51),
xrange(50,0,-1))])

but reduce is a functional way of doing it, what is the more pythonic
way of doing this?
