It's perfectly valid to use break - as others have pointed out, it's nowhere in the same league as goto. Although you might want to use the vFound variable when you want to check outside the loop whether the value was found in the array. Also from a maintainability point of view, having a common flag signalling the exit criteria might be useful.

2020年4月25日 · Another approach using a some lesser known but useful python control flows include using a for/else and try/except/else, it still requires a break but i think it's still a neat alternative

2012年12月21日 · The break/continue has to appear literally inside the loop. Your options are: return a value from funcA and use it to decide whether to break; raise an exception in funcA and catch it in the calling code (or somewhere higher up the call chain) write a generator that encapsulates the break logic and iterate over that instead over the range

There is no way to do this from a language level. Some languages have a goto others have a break that takes an argument, python does not. The best options are: Set a flag which is checked by the outer loop, or set the outer loops condition. Put the loop in a function and use return to break out of all the loops at once. Reformulate your logic ...

2014年6月5日 · In your old code, if the user entered "quit", the second if-statement would never be executed because the condition of the first passed.

I'm currently in Python 3.11.4, and all other solutions (list slicing, itertools.takewhile, short-circuiting any, the breaker iter, and the end thing by @recnac) still works. I find takewhile the most elegant and pythonic, however somehow I want to write some cursed one-liner, that actually breaks out of the list instead of skipping through the ...

2016年9月20日 · I am using Python 3.5, and I would like to use the break command inside a function, but I do not know how. I would like to use something like this: def stopIfZero(a): if int(a) == 0: b...

If is an expression, break similar to return is a statement. You can't use two statements in a single sentence (unless you use a semicolon which is ugly). I know it would have been really cool if we can do that, but alas that's the way it is.

2013年5月11日 · how to get the program to restart if user input is wrong; i.e. a break if but I couldn't work out how to do this despite searching around and testing a few a methods. I have left the rest of the code as it is insignificant effectively duplicate of the first set of multiplication using the preset figures.

This question was asked before Python 3.4 existed but with 3.4 you can use contextlib.supress, suppressing your own personal exception. See that this (runnable as is) code
