Single-Item Tuple Creation

The one function provides a cleaner alternative to Python’s comma-syntax for creating single-item tuples. It can be used directly from the package or installed into builtins.

Basic Usage

Import and use directly from the package:

>>> from frigid import one
>>> single42 = one( 42 )
>>> single42
(42,)

This is equivalent to the standard comma-syntax but more readable in many contexts:

>>> one( 42 ) == ( 42, )
True

Common Use Cases

Creating lists of single-item tuples is clearer with one:

>>> numbers = [ one( x ) for x in range( 3 ) ]
>>> numbers
[(0,), (1,), (2,)]

It works well with map and other higher-order functions:

>>> tuple( map( one, [ 'a', 'b', 'c' ] ) )
(('a',), ('b',), ('c',))

Installation

The function can be installed into builtins for easier access:

>>> from frigid import install
>>> install( )  # Installs as 'one'
>>> one( 'test' )   # Now available globally
('test',)
>>> install( 'single' )  # Install with custom name
>>> single( 'test' )
('test',)
