[FIXED] Generate a string from a dictionary keys (combinations) and assing a boolean value based on values

Issue

I have a structure similar, to a dictionary of dictionaries:

cont  = {

'perm': { 'r': False, 'rw': True}

'prig':  { 'sq': False, 'rot':False, 'rq':True}

'anon':  {'100': False, '500':True, '99':False; '400':False}

}

From this structure I need to generate a string from keys, and know if the string is False or True based on the values:

Example:

'perm', 'prig', 'anon' will become: 'r,sq,100' or 'rw,sq,100' or 'r,rq,100'.

1. I need to generate all permutations of the second level keys.
2. For each string, I need to associate a Boolean value using 'AND' are True or False. For the example above:

False,False,False -> False;  True,False,False -> True,False,True, False -> False;

Solution

Here is my take on the assignment. It has a lot more code than the answer from @Ajax1234 but I hope it is easier to understand/read for some.

import itertools
data = {
    'test': {'a': False, 'b': True},
    'perm': {'r': False, 'rw': True},
    'prig': {'sq': False, 'rq': True},
    'anon': {'100': False, '500': True},
}

# define the order of the keys
key_order = ('perm', 'prig', 'anon', 'test')

# build a list of iterables for the 'product()' function
iterables = [
    sorted(data[k].keys())
    for k in key_order]
print(iterables)

print()
print('{:3s} {:20s} {:30s} {}'.format('i', 'elements', 'value of elements', 'AND'))

for i, elements in enumerate(itertools.product(*iterables)):
    # get the values for all the elements, in the correct order
    values = [
        data[k][sub_k]
        for k, sub_k in zip(key_order, elements)]

    print('{:3d} {:20s} {:30s} {}'.format(
        i+1,
        ','.join(elements),
        str(values),
        all(values)))

This code gives me the following output:

[['r', 'rw'], ['rq', 'sq'], ['100', '500'], ['a', 'b']]

i   elements             value of elements              AND
  1 r,rq,100,a           [False, True, False, False]    False
  2 r,rq,100,b           [False, True, False, True]     False
  3 r,rq,500,a           [False, True, True, False]     False
  4 r,rq,500,b           [False, True, True, True]      False
  5 r,sq,100,a           [False, False, False, False]   False
  6 r,sq,100,b           [False, False, False, True]    False
  7 r,sq,500,a           [False, False, True, False]    False
  8 r,sq,500,b           [False, False, True, True]     False
  9 rw,rq,100,a          [True, True, False, False]     False
 10 rw,rq,100,b          [True, True, False, True]      False
 11 rw,rq,500,a          [True, True, True, False]      False
 12 rw,rq,500,b          [True, True, True, True]       True
 13 rw,sq,100,a          [True, False, False, False]    False
 14 rw,sq,100,b          [True, False, False, True]     False
 15 rw,sq,500,a          [True, False, True, False]     False
 16 rw,sq,500,b          [True, False, True, True]      False
