title: Python Slicing from the last space till end of string
body: <p>I have a string variable, something like</p>
  <p><code>new_str = &quot;8. [confusing] use python skills to slice -AB1 +AB2 +AAB&quot;</code>.</p>
  <p>I want to slice from the last letter till the end of the string. The last letter in this case should be <code>e</code> from the the word <code>slice</code> so the resulting string should be <code>-AB1 +AB2 +AAB</code> but I am not sure how to do so.</p>
  <p>I have tried this approach <code>new_str[new_str.rfind(' ') : ]</code>
  but it slices from the last space and returns <code>+AAB</code>.</p>
  <p>It would be great if someone could help me with this.</p>
