Filter

Syntax

filter(function, iterable)
itertools.ifilter(function, iterable)
future_builtins.filter(function, iterable)
itertools.ifilterfalse(function, iterable)
itertools.filterfalse(function, iterable)

Parameters

function | callable that determines the condition or None then use the identity function for filtering (positional-only)
iterable | iterable that will be filtered (positional-only)

Remarks

In most cases a comprehension or generator expression is more readable, more powerful and more efficient than filter() or ifilter().
