    return res_dct
         
# Driver code
lst = ['a', 1, 'b', 2, 'c', 3]
print(Convert(lst))

Example 2: python dictionary to array

dict = {"a": 1, "b": 2, "c": 3, "d": 4}

OUTPUT
[['a' '1']
 ['b' '2']
 ['c' '3']
 ['d' '4']]

Example 3: python list to dictionary

def to_dictionary(keys, values):
    return dict(zip(keys, values))
    
keys = ["a", "b", "c"]    
values = [2, 3, 4]
print(to_dictionary(keys, values)) 		# {'a': 2, 'c': 4, 'b': 3}

Example 4: python list of dictionaries to list

[d['value'] for d in l]

Example 5: python list of dictionaries to list
