创建一个条件语句片段(IfStatement)对象,并将其关联到代码片段对象。 创建一个循环语句片段(WhileLoop)对象,并将其关联到代码片段对象。 创建一个跳出循环语句片段(BreakStatement)对象,并将其关联到代码片段对象。 创建一个打印语句片段(PrintStatement)对象,并将其关联到代码片段对象。 创建一个Python对象,并将代码片...
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 »...
while loop-continuation-condition: statement(s) #eg: i = 1 while i < 10: print(i) i += 1 1. 2. 3. 4. 5. 6. 7. 循环设计策略: 确认需要循环的语句 将循环语句整合在一个循环中 编写循环继续条件并添加合适语句进行控制循环,避免无限循环 注意:执行循环经常会遇到偏离1的误差,比如想要循环100...
You can attach an optional else clause with while statement, in this case, syntax will be -while (expression) : statement_1 statement_2 ... else : statement_3 statement_4 ...The while loop repeatedly tests the expression (condition) and, if it is true, executes the first block of ...
Python中的while循环是一种迭代结构,用于重复执行一段代码块,直到指定的条件不再满足为止。它的语法形式为: ```python while 条件: # 循环体 ``` 在每次循环开...
When the condition is false, the loop terminates and subsequent statements indented at the same level as while are executed.如果通过 while 实现一个计数循环,需要在循环之前对计数器 idx 进行初始化,并在每次循环中对计数器 idx 进行累加,而在for循环中循环变量逐一取自遍历结构,不需要程序维护计数器。I...
First, create awhilewith a condition that is always true. The simplest way is shown. Using anifstatement, you define thestoppingcondition. Inside theif, you writebreak, meaning "exit the loop." The difference here is that this loop isguaranteedto run at least once. ...
The Python while loop can be used to execute a block of code for as long as a certain condition is fulfilled. While loops are primarily used in Python when the number of iterations can’t be determined at the time of writing the code. Keep reading to find out how the Python while ...
Anytime you have need to repeat a block of code a fixed amount of times. If you do not know the number of times it must be repeated, use a “while loop” statement instead. For loop Python Syntax The basic syntax of the for loop in Python looks something similar to the one mentioned...
