class TerminateLoop(Exception): pass try: for i in range(10): if i == 5: raise TerminateLoop print(i) except TerminateLoop: print("Loop terminated") 在上面的代码中,自定义异常TerminateLoop用于终止循环。当i等于5时,TerminateLoop异常被抛出,循环终止。 总结 在Python中,终止for循环的方法主要有使用...
class TerminateLoop(Exception): pass numbers = [1, 2, 3, 4, 5] try: for number in numbers: if number == 4: raise TerminateLoop print(number) except TerminateLoop: print("Loop terminated.") 在这个例子中,当number等于4时,引发TerminateLoop异常,循环终止,并捕获该异常。 其他方法 虽然break、r...
Break for loop Thebreak statementis used toterminate the loop. You can use the break statement whenever you want to stop the loop. Just you need to type the break inside the loop after the statement, after which you want to break the loop. ...
可能您可以使用threading模块中的计时器(https://docs.python.org/3/library/threading.html)。这是一个简单的例子: import subprocessimport threading def terminate(process): print('terminating process',process) process.kill() print('done') cmd = [<your command>, <your arguments>,...]process = subp...
We can use break statement to terminate the for loop if an odd number is present. We can print the sum in the else part so that it gets printed only when the for loop is executed normally. defprint_sum_even_nums(even_nums):total=0forxineven_nums:ifx%2!=0:breaktotal+=xelse:print...
