How to sort a list in Python?

You can use the `sort()` function to sort a list in Python. The `sort()` function rearranges the elements of the original list in a way that they follow an increasing or decreasing order.

Here is an example of sorting a list in ascending order:

```
numbers = [5, 1, 9, 3, 7]
numbers.sort()
print(numbers)

Output: [1, 3, 5, 7, 9]
```
If you want to sort a list in descending order, you can use the `reverse=True` parameter with the `sort()` function.

```
numbers = [5, 1, 9, 3, 7]
numbers.sort(reverse=True)
print(numbers)

Output: [9, 7, 5, 3, 1]
```
If you don’t want to modify the original list, you can use the `sorted()` function, which will create a new sorted list:

```
numbers = [5, 1, 9, 3, 7]
sorted_numbers = sorted(numbers)
print(sorted_numbers)

Output: [1, 3, 5, 7, 9]
```
You may also sort a list of strings:

```
names = [‘Alex’, ‘Charlie’, ‘Ben’]
names.sort()
print(names)

Output: [‘Alex’, ‘Ben’, ‘Charlie’]
```
