They are not recognized by the Python bytecode compiler and are not accessible as runtime object attributes (i.e. not assigned to __doc__), but two types of extra docstrings may be extracted by software tools:

The wrapped function is created internally by the decorator, any positional arguments are forwarded to the filter function. The first argument is always the value already converted into a string. If you're using Jinja with django and want to use the django filters in Jinja have a look at the developer recipies page. filter (function, iterable) It previously enabled universal newlines in text mode, which became the default behaviour in Python 3.0.

To register a nondeterministic Python function, users need to first build a nondeterministic user-defined function for the Python function and then register it as a SQL function. returnType can be optionally specified when f is a Python function but not when f is a user-defined function.

Test functions and filter functions live in their own namespace. Global functions not. They behave like normal objects in the context. Beside the functions added by the application or framewhere there are two functions available per default: range. Works like the python range function just that it doesn't support ranges greater than 1000000. debug 11/28/2011В В· I am trying to use Python's built-in filter function in order to extract data from certain columns in a CSV. Is this a good use of the filter function? Would I have to define the data in these columns first, or would Python somehow already know which columns contain what data?

registerFunction(name, f, returnType=StringType)В¶. Registers a python function (including lambda function) as a UDF so it can be used in SQL statements. In addition to a name and the function itself, the return type can be optionally specified. Similarly to map and filter above, in Python 3, the zip() function returns an iterator (specifically, a zip object). In Python 2, it returned a list. In Python 2, it returned a list. The Compatibility library: six library provides the iterator behavior under a name common to both Python versions, using the from six.moves import zip statement.

In functional programming, filter is a higher-order function that processes a data structure (usually a list) in some order to produce a new data structure containing exactly those elements of the original data structure for which a given predicate returns the boolean value true
