Python itertools.product module not working as expect when I'm extracting string "[1,2], [3,4], [5,6,7], [8,9]" from a json object here:
},
"combos_matrix": "[1,2], [3,4], [5,6,7], [8,9]"
},
But it's working when I put directly numbers in ():
list(itertools.product([1,2], [3,4], [5,6,7], [8,9]))
Here is my results when I extract data from json and try the function
Json sample:
},
"combos_matrix": "[1,2], [3,4], [5,6,7], [8,9]"
},
Code by using json object:
combos_matrix = map_json["world"]["combos_matrix"]
print(combos_matrix)
combos_list = list(itertools.product(combos_matrix))
print(combos_list)
Output:
[1,2], [3,4], [5,6,7], [8,9]
[('[',), ('1',), (',',), ('2',), (']',), (',',), (' ',), ('[',), ('3',), (',',), ('4',), (']',), (',',), (' ',), ('[',), ('5',), (',',), ('6',), (',',), ('7',), (']',), (',',), (' ',), ('[',), ('8',), (',',), ('9',), (']',)]
What I'm expecting and this is the result when I give the function directly the list of numbers:
Code:
combos_list = list(itertools.product([1,2], [3,4], [5,6,7], [8,9]))
print(combos_list)
Output:
[(1, 3, 5, 8), (1, 3, 5, 9), (1, 3, 6, 8), (1, 3, 6, 9), (1, 3, 7, 8), (1, 3, 7, 9), (1, 4, 5, 8), (1, 4, 5, 9), (1, 4, 6, 8), (1, 4, 6, 9), (1, 4, 7, 8), (1, 4, 7, 9), (2, 3, 5, 8), (2, 3, 5, 9), (2, 3, 6, 8), (2, 3, 6, 9), (2, 3, 7, 8), (2, 3, 7, 9), (2, 4, 5, 8), (2, 4, 5, 9), (2, 4, 6, 8), (2, 4, 6, 9), (2, 4, 7, 8), (2, 4, 7, 9)]
Can you help on this guy, I guess I'm missing something.
Extracting combos_matrix from JSON objects makes it a string representation of the list, but you need the actual list, you can get it from json.loads():
combos_matrix = map_json["world"]["combos_matrix"]
print(combos_matrix)
combos_matrix_json = f'[{combos_matrix}]'
combos_list = json.loads(combos_matrix_json)
combos_result = list(itertools.product(*combos_list))
print(combos_result)
Output:
[1,2], [3,4], [5,6,7], [8,9]
[(1, 3, 5, 8), (1, 3, 5, 9), (1, 3, 6, 8), (1, 3, 6, 9), (1, 3, 7, 8), (1, 3, 7, 9), (1, 4, 5, 8), (1, 4, 5, 9), (1, 4, 6, 8), (1, 4, 6, 9), (1, 4, 7, 8), (1, 4, 7, 9), (2, 3, 5, 8), (2, 3, 5, 9), (2, 3, 6, 8), (2, 3, 6, 9), (2, 3, 7, 8), (2, 3, 7, 9), (2, 4, 5, 8), (2, 4, 5, 9), (2, 4, 6, 8), (2, 4, 6, 9), (2, 4, 7, 8), (2, 4, 7, 9)]
