Python | Combining values from dictionary of list

Given a dictionary of list values, the task is to combine every key-value pair in every combination.

Input :
{“Name” : [“Paras”, “Chunky”],
“Site” : [“Geeksforgeeks”, “Cyware”, “Google”] }

Output:
[{‘Site’: ‘Geeksforgeeks’, ‘Name’: ‘Paras’}, {‘Site’: ‘Cyware’, ‘Name’: ‘Paras’},
{‘Site’: ‘Google’, ‘Name’: ‘Paras’}, {‘Site’: ‘Geeksforgeeks’, ‘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) 

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) 

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’}]]
