Accumulate function in python

2010-07-19 Thread dhruvbird
Hello, I have a list of integers: x = [ 0, 1, 2, 1, 1, 0, 0, 2, 3 ] And would like to compute the cumulative sum of all the integers from index zero into another array. So for the array above, I should get: [ 0, 1, 3, 4, 5, 5, 5, 7, 10 ] What is the best way (or pythonic way) to get this. Re

Why doesn't python's list append() method return the list itself?

2010-07-11 Thread dhruvbird
