In Python, we use awhileloop to repeat a block of code until a certain condition is met. For example, number =1whilenumber <=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 long as ...
The While statement is a type of loop statement. If the condition is met, the internal instruction is executed until the condition is not met. If the condition is not met, the internal instruction is not executed. Here is a piece of code to guess the number. To obtain random numbers, y...
而用 while，你需要一个 int 类型的索引 i，每次靠索引 i 自增来获取数，而int 类型在 Python 中...
Each Looping method isconditional. Conditional means that the instructions that you want to run will keep on running until some condition is being met or not stops meeting. A while loop iterates or keeps running instructions until the condition it uses stop being False. In other words, it kee...
In programming, loops are used to repeat a block of code until a specified condition is met. C programming has three types of loops. for loop while loop do...while loop In the previous tutorial, we learned about for loop. In this tutorial, we will learn about while and do..while ...
I am not sure what you are trying to do. You can implement a do-while loop like this: while True: stuff() if fail_condition: break Or: stuff() while not fail_condition: stuff() What are you doing trying to use a do while loop to print the stuff in the list? Why not just use...
Python whileTrue:if<expr1>:# One condition for loop terminationbreak...if<expr2>:# Another termination conditionbreak...if<expr3>:# Yet anotherbreak In cases like this, where there are multiple reasons to end the loop, it is often cleaner tobreakout from several different locations, rather...
In programming, a while loop is code that continuously repeats 0:01 until a certain condition is no longer met. 0:04 If I think about my day today, I've already used a few of these loops. 0:07 In the shower this morning, while there was soap on my body, I rinsed. 0:12 ...
4. If there are no more lines of code after the loop, the program terminates. While loops are commonly used when we want to repeat a certain block of code until a specific condition is met. The condition is typically a Boolean expression that evaluates to either true or false. If the ...
Is it true that the while statement is used to exit a program loop before the stopping condition is met? What is the difference between for-each loop and for loops in java? Which type of loop allows you to continuously repeat a section of code while a condition is satisfied? (a) If ...
