python do while
There is no do-while loop in Python. This is a similar construct, taken from the link above. while True: do_something() if condition(): break., Here's a very simple way to emulate a do-while loop: condition = True while condition: # loop body here condition = test_loop_condition() # end of loop. The key features of a do-while loop are that the loop body always executes at least once, and tha, While python doesn't explicitly allow do-while loops, there are at least 3 reasonable ways to implement them: 1) while True: #loop body if not expr(): break. 2) x = True while x: #loop body x = expr(). 3) def f(): #loop body f() while expr(): f(). No, This is a common way to emulate do-while: while True: # body if condition: break.,Python 循环语句本章节将向大家介绍Python的循环语句,程序在一般情况下是按顺序执行的。 编程语言提供了各种控制结构,允许更复杂的执行路径。 循环语句允许我们执行一个语句或语句组多次,下面是在大多数编程语言中的循环语句的一般形式: Python提供了for循环和while循环(在Python中没有do..while循环): 循环类型 ... ,Python While 循环语句Python 编程中while 语句用于循环执行程序,即在某条件下,循环执行某段程序,以处理需要重复处理的相同任务。其基本形式为: while 判断条件: 执行语句…… 执行语句可以是单个语句或语句块。判断条件可以是任何表达式,任何非零、或非空(null)的值均为true。 当判断条件假false时,循环结束。 执行流程图 ... , At times we encounter situations where we want to use the good old do-while loop in Python.
