title: In python s[:1] first one is ignored but s[:3] in this the third alphabet is included? s is a string
body: <p>Why in python while slicing a string suppose <code>s='hello'</code> we run command <code>s[1:]</code> and the result is 'ello'.First alphabet is ignored.But <code>s[:3]</code> gives result <code>'hel'</code>. 3rd alphabet should be ignored?</p>
