The slice of *s* from *i* to *j* with step *k* is defined as the sequence of
- items with index ``x = i + n*k`` such that 0 ≤n < (j-i)/(k). In other words,
+ items with index ``x = i + n*k`` such that ``0 <= n < (j-i)/k``. In other words,
the indices are ``i``, ``i+k``, ``i+2*k``, ``i+3*k`` and so on, stopping when
*j* is reached (but never including *j*). If *i* or *j* is greater than
``len(s)``, use ``len(s)``. If *i* or *j* are omitted or ``None``, they become
