不用非要从语义理解记忆,将while...else作为一组语句,正常语法执行完上面的while循环就执行下面的else语句,while循环被break终止就不执行下面的语句 2.5.简单语句组 类似if 语句的语法,如果while循环体中只有一条语句,可以将该语句与while写在同一行中, 如下所示: #!/usr/bin/pythonflag =1while(flag):print'G...
The for loop and while loop are two different approaches to executing the loop statements in python. They both serve the same functionality of looping over a python code till a condition is being fulfilled. For loops and while loops differ in their syntax. In while loops, we have to mention...
With Python, you can use while loops to run the same task multiple times and for loops to loop once over list data. In this module, you'll learn about the two loop types and when to apply each.Learning objectives After you've completed this module, you'll be able to: Identify when ...
In Python, you can use the break statement to exit a loop when a certain condition is met. This helps prevent infinite loops and allows for more control over loop execution. Emulating the Do-While Loop in Python In some programming languages, a "do-while" loop ensures that the code within...

while loops are commonly used to iterate an unknown number of times, which is useful when the number of iterations depends on a given condition.Python has both of these loops and in this tutorial, you’ll learn about for loops. In Python, you’ll generally use for loops when you need to...

Using a for loops in Python we can automate and repeat tasks in an efficient manner. So the bottom line is using the for loop we can repeat the block of statements a fixed number of times. Let’s understand this with an example. As opposed to while loops that execute until a condition...
