\begin{funcdesc}{groupby}{iterable\optional{, key}}
Make an iterator that returns consecutive keys and groups from the
- \var{iterable}. \var{key} is a function computing a key value for each
+ \var{iterable}. The \var{key} is a function computing a key value for each
element. If not specified or is \code{None}, \var{key} defaults to an
identity function and returns the element unchanged. Generally, the
iterable needs to already be sorted on the same key function.
\begin{funcdesc}{tee}{iterable\optional{, n=2}}
Return \var{n} independent iterators from a single iterable.
- The case where \var{n} is two is equivalent to:
+ The case where \code{n==2} is equivalent to:
