This is a normal while loop without break statements. The condition of the while loop is at the top and the loop terminates when this condition isFalse. Flowchart of Loop With Condition at Top Example #2: Loop with condition at the top # Program to illustrate a loop with the condition at...
图示化该过程,可以用以下Flowchart表示。 是否开始是否还有元素?处理元素结束 如图所示,循环过程不断检查可迭代对象中是否还有元素可处理。当可迭代对象中的元素被全部处理完后,循环自然结束。 3. 实际使用中的注意事项 3.1 嵌套for循环 在某些情况下,我们可能需要在for循环内部再使用一个for循环,通过嵌套的方式处理复...
flowchart TD; start(开始) --> input(输入初始值); input --> loop(循环); loop --> output(输出结果并保存到列表); output --> loop; loop --> condition(满足条件吗?); condition -- 是 --> output; condition -- 否 --> end(结束); 代码示例 下面是一个简单的示例代码,演示了如何将每次循...
Tip:We should update the variables used inconditioninside the loop so that it eventually evaluates toFalse. Otherwise, the loop keeps running, creating an infinite loop. Flowchart of Python while Loop Flowchart of Python while Loop Example: Python while Loop # Print numbers until the user enters...
For example the following code never prints out anything since before executing the condition evaluates to false. x = 10; while (x < 5): print(x) x += 1 CopyFlowchart: The following while loop is an infinite loop, using True as the condition:...
inner: IfTrue, the body of the field will be parsed as a nested flowchart. IfFalse, the body of the field will be parsed as a single node. simplify: IfTrue, simple If and Loop statements will be simplified. For example, an If statement with a single expression will be converted into...

Here’s the general syntax to create a for loop:Python for loop_var in iterable: # Repeat this code block until iterable is exhausted # Do something with loop_var... if break_condition: break # Leave the loop if continue_condition: continue # Resume the loop without running the ...
Since this condition is merely the True Boolean value, the execution enters the loop to ask the user to type your name again. See Figure 2-12 for the flowchart of this program. Run yourName2.py, and enter the same text you entered for yourName.py. The rewritten program should respond ...
