+   The outer-most leading and trailing *chars* argument values are stripped
+   from the string. Characters are removed from the left until
+   reaching a string character that is not contained in the set of
+   characters in *chars*. A similar action takes place on the right.
+   For example::
+
+      >>> comment_string = '#....... Section 3.2.1 Issue #32 .......'
+      >>> comment_string.strip('.#! ')
+      'Section 3.2.1 Issue #32'
