In Django, how does one filter a QuerySet with dynamic field lookups?
...'s argument expansion may be used to solve this problem:
kwargs = {
'{0}__{1}'.format('name', 'startswith'): 'A',
'{0}__{1}'.format('name', 'endswith'): 'Z'
}
Person.objects.filter(**kwargs)
This is a very common and useful Python idiom.

...works but it will leave a leading space: awk '{first = $1; $1 = ""; print $0, first; }'
You can also find the number of columns in NF and use that in a loop.
