How do I reverse a string in Python?

To reverse a string in Python, you can use several methods:

1. Using slicing: The most common way to reverse a string is by slicing it with a step of `-1`.

2. Using a loop: You can reverse a string by iterating through its characters in reverse order.

3. Using built-in functions: Functions like `reversed()` can reverse the string, which can then be joined into a new string.

Each method is efficient and commonly used based on the scenario.
