title: Omit one value from a range
body: <p>What's the most concise way in Python to write a range (generator or list) which omits one single value. So given integers <code>n</code>and <code>k</code> with <code>0</code>≤<code>k</code>&lt;<code>n</code> I want all the integers from <code>0</code> (inclusive) to <code>n</code> (exclusive) but without <code>k</code>.</p>
