Converting to Dictionary in Python
To convert any object to a dictionary, you need to apply the dict function. However, not all data types can become a dictionary. Let's try to convert a string and a list to a dictionary:
txt = '12345'
dct = dict(txt) # error
lst = ['1', '2', '3', '4', '5']
dct = dict(lst) # error
This is because the object must have paired values. Now let's create a dictionary from nested lists:
lst = [['a', '1'], ['b', '2']]
dct = dict(lst)
print(dct) # {'a': '1', 'b': '2'}
Nested tuples can also be converted into a dictionary:
tlp = ((1, 'a'), (2, 'b'))
dct = dict(tlp)
print(dct) # {1: 'a', 2: 'b'}
The following code is given:
tst = [[1, 'ab'], [2, 'cd'], [3, 'ef']]
dct = dict(tst)
print(dct)
Tell me what will be output to the console.
The following code is given:
tst = [('x', 2), ('y', 4), ('z', 6)]
dct = dict(tst)
print(dct)
Tell me what will be output to the console.
The following code is given:
tst = ['a', 'b', 'c', 'd']
dct = dict(tst)
print(dct)
Tell me what will be output to the console.
The following code is given:
tst = ('a', 1), ('b', 2), ('c', 3)
dct = dict(tst)
print(dct)
Tell me what will be output to the console.
