You're starting a new function to parse CSV files. Instead of typing everything manually:
182141

183-
| Action | Windows/Linux | macOS |
184-
|--------|------------------|-------|
185-
| Accept Suggestion | `Tab` | `Tab` |
186-
| Dismiss Suggestion | `Escape` | `Escape` |
187-
| Request Suggestion | `Alt + \` | `⌥ \` |
188-
| Open Copilot Chat | Click icon or `Ctrl + Alt + I` | `⌘ ⌥ I` |
142+
1. Write a descriptive comment:
143+
```python
144+
# Function to parse a CSV file and return a list of dictionaries
145+
def parse_csv(file_path):
146+
```

Copilot's suggestions improve with clear context. Here's how:
151+
### Use Case 2: Refactoring Legacy Code
193152

194-
**❌ Vague:**
195-
```javascript
196-
// process data
197-
function process(data) {
198-
```
199-
200-
**✅ Clear:**
201-
```javascript
202-
// Filter array to include only items with quantity > 0, then sort by price ascending
203-
function filterAndSortByPrice(products) {
204-
```
205-
206-
With the second approach, Copilot generates more accurate code.

You have a messy function that needs improvement:

## Common Use Cases
209-
210-
### Use Case 1: Boilerplate Code
211-
212-
Instead of typing repetitive code, let Copilot do the heavy lifting:
213-
214-
```java
215-
// Create a POJO with getters and setters
216-
public class User {
217-
private String name;
218-
private String email;
219-
// Copilot will suggest getter/setter methods
220-
}
221-
```
222-
223-
### Use Case 2: Algorithm Implementation
224-
225-
Ask Copilot to implement algorithms:
226-
227-
```python
228-
# Implement bubble sort algorithm
229-
def bubble_sort(arr):
230-
# Copilot suggests the complete implementation
231-
```
155+
1. Highlight the function
156+
2. Open Copilot Chat and ask: "Refactor this function to be more readable and efficient"
157+
3. Copilot suggests improvements
158+
4. Apply the changes
