Dictionaries

1. Populating a dictionary

Create a dictionary by using all the given variables.

first_name = 'John'
last_name = 'Doe'
favorite_hobby = 'Python'
sports_hobby = 'gym'
age = 82

# Your implementation
my_dict = 

  Cell In[2], line 2
    my_dict =
              ^
SyntaxError: invalid syntax

assert my_dict == {
        'name': 'John Doe',
        'age': 82,
        'hobbies': ['Python', 'gym']
    }

2. Accessing and merging dictionaries

Combine dict1, dict2, and dict3 into my_dict. In addition, get the value of special_key from my_dict into a special_value variable. Note that original dictionaries should stay untouched and special_key should be removed from my_dict.

dict1 = dict(key1='This is not that hard', key2='Python is still cool')
dict2 = {'key1': 123, 'special_key': 'secret'}
# This is also a away to initialize a dict (list of tuples) 
dict3 = dict([('key2', 456), ('keyX', 'X')])

# 'Your impelementation'
my_dict = 
special_value = 

assert my_dict == {'key1': 123, 'key2': 456, 'keyX': 'X'}
assert special_value == 'secret'

# Let's check that the originals are untouched
assert dict1 == {
        'key1': 'This is not that hard',
        'key2': 'Python is still cool'
    }
assert dict2 == {'key1': 123, 'special_key': 'secret'}
assert dict3 == {'key2': 456, 'keyX': 'X'}
