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 ...

One thing we should remember that a while loop tests its condition before the body of the loop (block of program statements) is executed. If the initial test returns false, the body is not executed at all. For example the following code never prints out anything since before executing the ...
通过在while循环内部设置一个计数器变量,每次循环时递增计数器,直到计数器达到指定次数为止。下面是一个示例代码: # 初始化计数器 count = 0 设置循环次数 max_count = 10 while循环,条件为计数器小于最大值 while count < max_count: print(f"This is loop number {count + 1}") # 计数器递增 count +=...
