1 2 3 4 In this example, the iteration goes through the list in the definition order, starting with 1 and ending with 4. Note that to iterate over a sequence in Python, you don’t need to be aware of the index of each item as in other languages where loops often rely on indices...

Let’s see the use for loop in Python. Definite Iteration: When we know how many times we wanted to run a loop, then we use count-controlled loops such as for loops. It is also known as definite iteration. For example, Calculate the percentage of 50 students. here we know we need ...
循环控制语句可以更改语句执行的顺序。Python支持以下循环控制语句: break结束全部循环,跳出整个循环 continue结束本次循环,进入下次循环 shell脚本里用break2可以跳出2层循环,但python不可以,这不是好语法,会造成语义混乱 回到顶部 2.while循环 参考文章: http://www.runoob.com/python/python-while-loop.html ...
