Here, the condition of the while loop is alwaysTrue. However, if the user entersend, the loop termiantes because of thebreakstatement. Pythonwhileloop with anelseclause In Python, awhileloop can have an optionalelseclause - that is executed once the loop condition isFalse. For example, coun...
In Python, a basic while loop looks like this: while[a conditionisTrue]: [do something] The condition we provide to the while statement is the controlling expression, our loop will run until the controlling statement is no longer true. ...
Python >>>number=5>>>whilenumber!=0:...ifnumber<=0:...break...print(number)...number-=2...531 This loop has the same original loop condition. However, it includes a failsafe condition in the loop body to terminate it in case the main condition fails. ...
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 program block. The condition is checked every time at the beginning of ...
Python中使用while循环的核心方法包括:设定循环条件、确保循环条件会在循环内部得到更新、使用break语句控制循环中断、使用continue语句跳过当前循环并进入下一次迭代。这些方法可以有效地控制循环执行的逻辑和次数。 1. 设定循环条件是while循环的基础,通过设定一个初始值和循环条件,可以控制循环的执行。例如: ...
The while Loop With thewhileloop we can execute a set of statements as long as a condition is true. ExampleGet your own Python Server Print i as long as i is less than 6: i =1 whilei <6: print(i) i +=1 Try it Yourself »...
If the condition of a while loop is always true or the variables within the loop do not update correctly, it may result in an infinite loop. An example of an infinite loop is: while True: # Infinite loop, no break condition Powered By In Python, you can use the break statement to ...
The While Loop In Python The while loop statement is used to repeat a block of code till a condition is fulfilled. When we don’t know the exact number of times, a loop statement has to be executed. We make use of while loops. This way, till the test expression holds true, the loo...
while loop-continuation-condition: # Loop body Statement(s) 当loop-continuation-condition为True时,则重复执行while中的语句,直到loop-continuation-condition为False时为止。 使用while语句 current_number = 1 # 当current_number 大于4时,则退出while循环 # 否则就循环打印当前数字 while current_number <= 4:...
while (condition) { // code block to be executed } 在这个语法中,condition是一个布尔表达式,代表循环条件。code block是需要重复执行的代码块。 While-loop的优势在于它可以根据条件动态地控制循环次数,使得程序能够灵活地处理不同的情况。它常用于需要重复执行某段代码直到满足特定条件的情况下,例如遍历数组、处...
