This kind of loop can be implemented using an infinite loop along with a conditional break in between the body of the loop. Flowchart of Loop with Condition in Middle Example #3: Loop with condition in the middle # Program to illustrate a loop with condition in the middle.# Take input fr...
the condition will still beTrueagain and thus the statement will be executed again. This will keep on happening and as you might have guessed there will be no end for this loop. Such kind of looping is calledinfinite loop
事实上,你几乎从来不希望你的程序从第一行代码开始,简单地执行每一行,一直到最后。流程控制语句可以决定在什么条件下执行哪些Python指令。 这些流程控制语句直接对应于流程图中的符号,所以我将提供本章中讨论的代码的流程图版本。图 2-1 显示了下雨时该做什么的流程图。沿着箭头所指的路线从头到尾走。 图2-1:告诉...
The while loop is one of the first loops that you'll probably encounter when you're starting to learn how to program. It is arguably also one of the most intuitive ones to understand: if you think of the name of this loop, you will quickly understand that the word "while" has got ...
Press Ctrl-C to stop this infinite loop!!! Traceback (most recent call last): File "<pyshell#1>", line 2, in <module> print('Press Ctrl-C to stop this infinite loop!!!') File "C:\Program Files\Python 3.5\lib\idlelib\PyShell.py", line 1347, in write return self.shell.write...
Here is how the above program works: It asks the user to enter a number. If the user enters a number other than0, it is printed. If the user enters0, the loop terminates. Infinite while Loop If the condition of awhileloop always evaluates toTrue, the loop runs continuously, forming ...
If, however, you were to remove the ‘i = i + 1’ part, thewhilecondition will never exit, as the number will never reach 100. These type ofwhileloops iterate endlessly and the program will probably crash eventually. This is called aninfinite loop. ...
Loops are used to repeatedly execute a block of program statements. The basic loop structure in Python is while loop. Here is the syntax.Syntax:while (expression) : statement_1 statement_2 ...The while loop runs as long as the expression (condition) evaluates to True and execute the prog...
this code, you have to pressCtrl+C, which interrupts the program’s execution from the keyboard. Otherwise, the loop would run indefinitely since its condition never turns false. In real-world code, you’d typically want to have a proper loop condition to prevent unintended infinite execution....
