`astropy.extern.configobj.validate:force_list`

source: /astropy/extern/configobj/validate.py :1227

Signature

def force_list ( value , min = None , max = None )

Summary

Check that a value is a list, coercing strings into a list with one member. Useful where users forget the trailing comma that turns a single value into a list.

Extended Summary

You can optionally specify the minimum and maximum number of members. A minumum of greater than one will fail if the user only supplies a string.

>>> vtor.check('force_list', ())
[]
>>> vtor.check('force_list', [])
[]
>>> vtor.check('force_list', 'hello')
['hello']
