Given a dictionary of list values, the task is to combine every key-value pair in every combination.
Input :
{“Name” : [“Paras”, “Chunky”],
“Site” : [“Geeksforneveropen”, “Cyware”, “Google”] }Output:
[{‘Site’: ‘Geeksforneveropen’, ‘Name’: ‘Paras’}, {‘Site’: ‘Cyware’, ‘Name’: ‘Paras’},
{‘Site’: ‘Google’, ‘Name’: ‘Paras’}, {‘Site’: ‘Geeksforneveropen’, ‘Name’: ‘Chunky’},
{‘Site’: ‘Cyware’, ‘Name’: ‘Chunky’}, {‘Site’: ‘Google’, ‘Name’: ‘Chunky’}]
Method #1: Using itertools and sorting
# Python code to combine every key value # pair in every combinations # List initialization Input = { "Bool" : ["True", "False"], "Data" : ["Int", "Float", "Long Long"], } # Importing import itertools as it # Sorting input sorted_Input = sorted(Input) # Using product after sorting Output = [dict(zip(sorted_Input, prod)) for prod in it.product(*(Input[sorted_Input] for sorted_Input in sorted_Input))] # Printing output print(Output) |
[{‘Bool’: ‘True’, ‘Data’: ‘Int’}, {‘Bool’: ‘True’, ‘Data’: ‘Float’}, {‘Bool’: ‘True’, ‘Data’: ‘Long Long’}, {‘Bool’: ‘False’, ‘Data’: ‘Int’}, {‘Bool’: ‘False’, ‘Data’: ‘Float’}, {‘Bool’: ‘False’, ‘Data’: ‘Long Long’}]
Method #2: Using Zip
# Python code to combine every key value # pair in every combinations # Importing import itertools # Input Initialization Input = { "Bool" : ["True", "False"], "Data" : ["Int", "Float", "Long Long"], } # using zip and product without sorting Output = [[{key: value} for (key, value) in zip(Input, values)] for values in itertools.product(*Input.values())] # Printing output print(Output) |
[[{‘Data’: ‘Int’}, {‘Bool’: ‘True’}], [{‘Data’: ‘Int’}, {‘Bool’: ‘False’}], [{‘Data’: ‘Float’}, {‘Bool’: ‘True’}], [{‘Data’: ‘Float’}, {‘Bool’: ‘False’}], [{‘Data’: ‘Long Long’}, {‘Bool’: ‘True’}], [{‘Data’: ‘Long Long’}, {‘Bool’: ‘False’}]]
