The overhead of simply adding atryblock but never throwing an exception The overhead of using an exception vs. comparable code without exceptions When the exception case is quite likely When the exception case is unlikely The first is easy to measure. We'll time two code blocks using thetime...
Using a for loop is one of Python’s most straightforward approaches to iterating along an iterator. Moreover, when the StopIteration exception occurs, a for loop will automatically catch and end it without throwing an exception. Here is an illustration of how to move through a list of intege...
