Question

Given a list of values:

data = [100, 80, 200, 20, 300, 100, 400, 40, 500, 120, 600, 60]

I want to extract the first two and the last two values, and create a new list. Unfortunately, the way I’m doing things right now, I get a list which contains two lists:

bla = [data[0:2], data[-2:]]

print bla
 [[100, 80], [600, 60]]

Instead I would like to get this:

[100, 80, 600, 60]

Is there an easy way of doing this?

(this question is somewhat related to this question, but I still think it’s different enough)

Answer 1

Use list concatenation with +:

data[0:2] + data[-2:]
