[FIXED] Converting/Merging a dictionary based on 2nd dictionary

Issue

I am on Python 3.9

What I have is two dictionaries.

dict1= {'ZS': [1, 2], 'ZP': [3], 'XS': [4, 5], 'XP': [6, 7]}
dict2= {'a': {}, 'b' : {}}

how do I take every two keys of dict1 and add them as dict-value in dict2.

Like below

required dict

result_dict= {'a': {'ZS': [1, 2], 'ZP': [3]}, 'b' : {'XS': [4, 5], 'XP': [6, 7]}}

Solution

You could do something like:

keys1 = list(dict1)
keys2 = list(dict2)
result_dict = {
    keys2[i]: {
        keys1[2*i]:dict1[keys1[2*i]], 
        keys1[2*i+1]:dict1[keys1[2*i+1]]
    } 
    for i in range(len(keys2))
}

But in my opinion it is a really bad habit to trust dictionary key's order (unless you use OrderedDict)
