I use sage range function to print numbers form 1 to say 10 using print [1..10]. How to print only even numbers using this?

Is the following ok?

sage: print range(2,11,2)
[2, 4, 6, 8, 10]

I knew that. I was wondering if same can be done with [1..10]?

The ellipsis operator looks at the previous two numbers to guess the step.

sage: [2, 4 .. 10]
[2, 4, 6, 8, 10]

using list comprehension:

sage: [i for i in [1..10] if i%2==0]
[2, 4, 6, 8, 10]

see more alternatives in the Programming in Python and Sage Thematic Tutorial.
