What should supposedly happen in your `try...else` example? do you mean `try...finally`? – DeepSpace Mar 17 '19 at 13:17

@DeepSpace When any wrong not happened, I want to execute the else block. But try...finally will always be executed. – overflow Mar 17 '19 at 13:22

What's wrong with `except: pass`? It's just 12 characters, no harm in typing it. :P It also makes the code more readable (e.g. "Here, I will pass the exception..."). – TrebledJ Mar 17 '19 at 13:25

And what should happen when something wrong **does** happen? The Python motto says "explicit is better than implicit". If you want to ignore an exception you must explicitly say so. – DeepSpace Mar 17 '19 at 13:28

If it was supported, the syntax
try:
something may go wrong...
else:
others func...
would be exactly equivalent in behaviour to
something may go wrong...
others func...
i.e. you do not need any special syntax for it

but if "something may go wrong..." went wrong, i just want to ignore it instead of raise it. – overflow Mar 17 '19 at 13:24

@Tr0y So ignore it with `except: pass` just like you are doing in the first example. This is how exceptions are ignored in Python – DeepSpace Mar 17 '19 at 13:30

@Tr0y then the syntax is wrong. To catch the thrown exception you need to have an `except`, not an `else`. an `else` block serves only to execute code after the try block ended without an exception thrown... – Antti Haapala -- Слава Україні Mar 17 '19 at 13:30
