Understanding the Code
The provided code snippet is designed to manipulate a dictionary in Python. Let's break it down step by step.
Code Breakdown
- The dictionary is defined as follows:
python
my_dict = {name: John, age: 25, city: New York}
The correct way to define this dictionary should use quotes for the keys and values:
python
my_dict = {'name': 'John', 'age': 25, 'city': 'New York'}
- The next line of code:
python
del my_dict[age]
This line attempts to delete the key `age` from `my_dict`. If the dictionary were defined correctly, `del my_dict['age']` would remove the key-value pair associated with `age`.
Expected Output
- After executing the deletion, the remaining dictionary would look like this:
python
{'name': 'John', 'city': 'New York'}
This matches option 'A'.
Conclusion
- The final print statement:
python
print(my_dict)
This will output:
python
{'name': 'John', 'city': 'New York'}
- Therefore, the correct answer is option 'A':
python
{name: John, city: New York}
This explanation highlights the importance of correct syntax in defining dictionaries and demonstrates how to properly delete key-value pairs.
