PHP to Python

[mapg]

For Python could use itertools combinations().

import itertools as it
from pprint import pprint

my_dict = {'item1':['A', 'B'], 'item':['C', 'D'], 'item3':['E','F']}
combinations = it.product(*(my_dict[name] for name in my_dict))
all_combo = list(combinations)
print(f'size={len(all_combo)}')
pprint(all_combo)

Output:
size=8
[('A', 'C', 'E'),
 ('A', 'C', 'F'),
 ('A', 'D', 'E'),
 ('A', 'D', 'F'),
 ('B', 'C', 'E'),
 ('B', 'C', 'F'),
 ('B', 'D', 'E'),
 ('B', 'D', 'F')]

The answer is very good but unfortunately, the keys are lost, and I need them.

How can be preserved the output that PHP version is showing but using Python?, namely ...

Output:
array (size=8)
  0 => 
    array (size=3)
      'item1' => string 'A' (length=1)
      'item2' => string 'C' (length=1)
      'item3' => string 'E' (length=1)
  1 => 
    array (size=3)
      'item1' => string 'A' (length=1)
      'item2' => string 'C' (length=1)
      'item3' => string 'F' (length=1)
  2 => etc ...
