Why does range(start, end) not include end?

Question

>>> range(1,11)

gives you

[1,2,3,4,5,6,7,8,9,10]

Why not 1-11?

Did they just decide to do it lik

Answer 1

The length of the range is the top value minus the bottom value.

It's very similar to something like:

for (var i = 1; i < 11; i++) {
    //i goes from 1 to 10 in here
}

in a C-style language.

Also like Ruby's range:

1...11 #this is a range from 1 to 10

However, Ruby recognises that many times you'll want to include the terminal value and offers the alternative syntax:

1..10 #this is also a range from 1 to 10
