In python 3, try/except was 25 % faster than if key in d: It'll let you catch the exception when it happens, but the rest of the block is never executed. Honestly, i've never found a need.
For the standard c++ code you write you should always use try / catch and not __try /.
Once you enter the try/finally block, the code in the finally section is guaranteed to run, no matter what happens between try and finally. For cases where the key was in the dictionary. 17 'continue' is allowed within an 'except' or 'finally' only if the try block is in a loop. It was much slower when the key wasn't in the dictionary, as expected, and.
A try block is not there to suppress exceptions across all code executed. Try / catch is what the c++ standard specifies for handling general c++ exceptions. 'continue' will cause the next iteration of the loop to start. If not you can try 3rd part library that has it (dunno which) or making a task listener that would search for.
