def main(): try: int('string_for_ValueError') except ValueError: print('How to stop further execution right here?') print('Executed') main() 如你所见, 无论何时, 每次都会执行print(‘Executed’)行。我的目标是在捕获ValueError之后立即停止当前函数的执行。 所以, 问题是-怎么做? 更新 此函数是...

How can we fix a stop iteration error python? Stop iteration error python handling is done with the try-except block. It would also help you comprehend how Python iterators operate to learn StopIteration Exception. An iterator object contains values that one can iterate upon. Additionally, it ad...
