• count([n])

   

  Return consecutive integers starting with n

   

  ifilter(predicate, iterable)

   

  Return all elements x of iterable for which predicate(x) is true.

   

  imap(function, *iterables)

   

  Like map(), but returns an iterator rather than a list.

   

  izip(*iterables)

   

  Like zip(), except it returns an iterator.

   

  repeat(obj)

   

  Returns an iterator that yields obj an unlimited number of times.

   

  times(n, [object])

   

  Returns object a total of n times.
