Combine Python Dictionary Permutations into List of Dictionaries

Question

Given a dictionary that looks like this:

{
    \'Color\': [\'Red\', \'Yellow\'],
    \'Size\': [\'Small\', \'Medium\', \'Large\']
}

How can

Answer 1

You can obtain that result doing this:

x={'Color': ['Red', 'Yellow'], 'Size': ['Small', 'Medium', 'Large']}
keys=x.keys()
values=x.values()

matrix=[]
for i in range(len(keys)):
     cur_list=[]
     for j in range(len(values[i])):
             cur_list.append({keys[i]: values[i][j]})
     matrix.append(cur_list)

y=[]
for i in matrix[0]:
     for j in matrix[1]:
             y.append(dict(i.items() + j.items()))

print y

result:

[{'Color': 'Red', 'Size': 'Small'}, {'Color': 'Red', 'Size': 'Medium'}, {'Color': 'Red', 'Size': 'Large'}, {'Color': 'Yellow', 'Size': 'Small'}, {'Color': 'Yellow', 'Size': 'Medium'}, {'Color': 'Yellow', 'Size': 'Large'}]
