I have the necessity to convert a multidimensional dictionary (as a database fetchall function returns) to a multidimensional list:
Multidimensional dictionary (fetchall-type)
multi_dict = [
'key1': 'value1', 'key2': 'value2', 'key3': 'value3',
'key1': 'value10', 'key2': 'value20', 'key3': 'value30'
]
Multidimensional list (output wanted)
multi_list = [
['value1', 'value2', 'value3']
['value10', 'value20', 'value30']
]
python multidimensional-array

[entry.values() for entry in multi_dict.items()] or simply iterate over your multi_dict and add the values of your list to your multi_list if i get your question right.

You just need to extract values from each dictionary in loop (in this example I used list comprehension).
multi_list = [list(d.values()) for d in multi_dict]
list(d.values()) is there because in python3, .values() returns dict_values object, not list so in python2 this can be omited and you can just do multi_list = [d.values() for d in multi_dict].
