![## Nested Dictionary Example
Suppose we have the following nested dictionary:
```python
root = {
'labs': {
'lab1.txt': 223,
'lab2.txt': 251,
'lab3.txt': 317,
},
'hws': {},
'plans': {
'vacation.txt': 636,
'evil': {
'world_domination.txt': 766
}
},
'resume.txt': 607,
'cat.jpg': 607
}
```
### Task
Write a line of code that adds the key-value pair `'lab4.txt': 142` to the dictionary associated with the key `'labs'`.
### Solution
To add the new key-value pair to the dictionary, use the following line of code:
```python
root['labs']['lab4.txt'] = 142
```
This code will insert the specified key-value pair into the nested dictionary under the `'labs'` key.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6fc09ca6-cf80-4929-a335-dec91559848e%2F6d3046ab-d7d8-438b-a954-57fc02f34a75%2Fyuug69t_processed.jpeg&w=3840&q=75)
