What are the performance implications of using `try...except` vs. `dict.get()` for key access?

Generally, `dict.get()` is slightly faster than `try...except` blocks for simple key access. This is because exception handling has some overhead. However, the performance difference is usually negligible unless you are performing a very large number of key accesses within a performance-critical section of your code. Readability and maintainability should often be prioritized over minor performance gains. If you are truly concerned about performance, benchmark both approaches in your specific use case.
