A for loop is primarily used for **repeating actions multiple times**. It allows you to execute a block of code a specified number of times, making it an efficient way to iterate over a sequence (like a list or a range of numbers) and perform the same operation for each item during each iteration.
The other options provided do not accurately describe the main use of a for loop:
- **Storing data for later use**: This is typically done using data structures like lists or arrays, rather than a for loop.
- **Naming items in a list**: While a for loop can iterate through the names of items in a list, it doesn't inherently name them.
- **Stopping a program when an error occurs**: Error handling is usually managed by try-except blocks or similar constructs, not through a for loop.
Thus, the correct answer is that for loops are used for repeating actions multiple times.
