File"iteration.py", line32,in<module>print(next(itrtr)) File"iteration.py", line19,in__next__raiseStopIteration StopIteration 我们实例化了MyIterator,然后为了获取它的值,我们多次调用了next()。当序列到头时,next()会抛出异常StopIteration。Python 中的for循环使用了同样的机制,它调用迭代器的next(),通...
As we see from the above code that when the number 2 is encountered, the iteration is skipped and we skip to the next iteration without disrupting the flow of the code. Special Case: Using exception handling. Exception handling is done with the try and the catch statements in Python. Excep...
The Pythoncontinuestatement is used in a loop (for or while) to skip the current iteration and move on to the next iteration. It is used to skip when a certain condition is satisfied and move on to the next iteration of the loop. The code following thecontinuestatement in the current it...
revisit old projects or exercises and try to improve them or do them in a different way. This could mean optimizing your code, implementing a new feature, or even just making your code more readable. This process of iteration will help reinforce what you've learned and show you how much ...

For example, when you are running a loop and want to skip the part of that iteration that can throw an exception. Use the try-except Statement With continue to Skip Iterations in a Python Loop In Python, exceptions can be easily handled through a try-except statement. If you think that ...
The continue statement instructs a loop to continue to the next iteration. Any code that follows the continue statement is not executed. Unlike a break statement, a continue statement does not completely halt a loop. You can use a continue statement in Python to skip over part of a loop wh...
在预训练阶段,BERT使用了两种任务来学习语言表示:掩码语言模型(Masked Language Model,MLM)和下一句预测(Next Sentence Prediction,NSP)。通过这两种任务,BERT能够学习到上下文感知的词嵌入和句子级别的语义表示。 在实际应用中,BERT的预训练模型可以用于各种下游任务,如文本分类、命名实体识别、问答系统等。通过微调预...

Just as with while loops, the continue statement can also be used in Python for loops to terminate the ongoing iteration and transfer the control to the beginning of the loop to continue the next iteration. Python 1 2 3 4 5 6 7 number_list = [2,3,4,5,6,7,8] for i in number...
