Question

Consider a dictionary,

dictionary = {
   'AE':{'Applied':4, 'Programming':3 }, 
   'BE':{'Applied':4, 'Programming':2 }, 
   'CE':{'Applied':4, 'Programming':5 },
}

With comprehension in definition, yield the output as,

output = [['AE':'BE':'CE'], 
          ['Applied', 2,4,5],
          ['Programming', 5,3,2]]

Answer 1

You can use this code:

dictionary = {
   'AE':{'Applied':4, 'Programming':3 }, 
   'BE':{'Applied':4, 'Programming':2 }, 
   'CE':{'Applied':4, 'Programming':5 },
}

output = []
dict_keys = list(dictionary.keys())
output.append(dict_keys)

for key in dictionary[dict_keys[0]]:
    value = [dictionary[k][key] for k in dict_keys]
    value.insert(0, key)
    output.append(value)

Output:

output = [['AE', 'BE', 'CE'], ['Applied', 4, 4, 4], ['Programming', 3, 2, 5]]
