# This is a program to illustrate the useage of continue in Python. # If you want to stop executing the current iteration of the loop and skip ahead to the next # continue statement is what you need. # *** for i in range (1,6): print print 'i=',i, print 'Hello,how', if i...
如果它等于6,我们将使用continue语句继续下一次迭代而不打印任何内容,否则我们将打印该值。 以下是上述想法的实现: # Python program to # demonstrate continue # statement # loop from 1 to 10 for i in range ( 1 , 11 ): # If i is equals to 6, # continue to next iteration # without printing...
迭代对象:就是一个具有next()方法的对象,obj.next()每执行一次,返回一行内容所有内容迭代完后, 迭代器引发一 个 StopIteration 异常告诉程序循环结束. for 语句在内部调用 next() 并捕获异常. for循环遍历迭代器或可迭代对象与遍历序列的方法并无二致,只是在内部做了调用迭代器next(),并捕获异常,终止循环的操作 ...

The continue statement with for loop We can use continue statements inside a for loop to skip the execution of the for loop body for a specific condition. Let’s say we have a list of numbers and we want to print the sum of positive numbers. We can use the continue statements to skip...
continuecan only be used within thefororwhileloop body, and it continues to the next iteration of the loop. Inside the loop we can use it anywhere, generally, we put it inside theif..elsecondition so it can only execute for specific conditions not for every iteration. ...
