Coding Life - While Loop
图6-5-1 brak 和 continue 语句用 break 语句将前面“死循环”的程序改造如下: #coding:utf-8 ''' whileloop.py ''' n = 0 while 1...执行效果: % python whileloop.py laoqi laoqi loop end 对照程序代...
i.e., for loop and while loop. You may have used both the “for” and “while” loop in your programs while coding. But have you ever tried to use the loop on a single line with all its working?
有一种循环叫死循环,一经触发,就运行个天荒地老、海枯石烂。 海枯石烂代码 1 2 3 4 5 count=0 whileTrue: print("你是风儿我是沙,缠缠绵绵到天涯...",count) count+=1 其实除了时间,没有什么是永恒的,死loop还是少写为好 上面的代码循环100次就退出吧 1 2 3 4 5 6 7 8 count=0 whileTrue: ...

前面讲解了顺序结构和选择结构,本节开始讲解循环结构。所谓循环(Loop),就是重复地执行同一段代码,例如要计算 1+2+3+……+99+100 的值,就要重复进行 99 次加法运算。 C语言while循环 while循环的一般形式为: while(表达式){ 语句块 } 意思是,先计算“表达式”的值,当值为真(非 0)时, 执行“语句块”;执...
I have while loop in following coding. it count data for a year. i am no able to take all one year data. It just shows last answer. I also tried double command it doesn't work too. Please help me how to take all one year data. ...
In Python, we use awhileloop to repeat a block of code until a certain condition is met. For example, number = 1 while number <= 3: print(number) number = number + 1 Output 1 2 3 In the above example, we have used awhileloop to print the numbers from1to3. The loop runs as...
