psweep.psweep.pgrid(plists)[source]#

Convenience function for the most common loop: nested loops with itertools.product: ps.itr2params(itertools.product(a,b,c,...)).

Parameters:

plists (Sequence[Sequence[dict]]) – List of plist() results. If more than one, you can also provide plists as args, so pgrid(a,b,c) instead of pgrid([a,b,c]).

Return type:

Sequence[dict]

Notes

For a single plist arg, you have to use pgrid([a]). pgrid(a) won’t work. However, this edge case (passing one plist to pgrid) is not super useful, since

>>> a=ps.plist("a", [1,2,3])
>>> a
[{'a': 1}, {'a': 2}, {'a': 3}]
>>> ps.pgrid([a])
[{'a': 1}, {'a': 2}, {'a': 3}]

Examples

>>> a = ps.plist('a', [1,2])
>>> b = ps.plist('b', [77,88])
>>> c = ps.plist('c', ['const'])
>>> # same as pgrid([a,b,c])
>>> ps.pgrid(a,b,c)
[{'a': 1, 'b': 77, 'c': 'const'},
 {'a': 1, 'b': 88, 'c': 'const'},
 {'a': 2, 'b': 77, 'c': 'const'},
 {'a': 2, 'b': 88, 'c': 'const'}]

>>> ps.pgrid(zip(a,b),c)
[{'a': 1, 'b': 77, 'c': 'const'},
 {'a': 2, 'b': 88, 'c': 'const'}]
