The else statement is a way to execute an alternative set of code if the condition returns “false.” Basically, the if else statement says “if this condition is true, execute the code in the first block of code. If the condition is false, then execute the code located in the else bl...

statement1 else if(表达式2)statement2 else if(表达式3)statement3 ……else statementN 解析：如果表达式1非0，则执行statement1，执行完退出语句；如果表达式2非0，则执行statement2，执行完退出语句；如果表达式3非0，则执行statement3，执行完退出语句；如果表达式4非0，则执行statement4，执行完退出语句；……如...
总结:在if条件语句中,要严格按照语法来书写代码,if语句条件成立执行的代码是带有缩进4格的代码块,而没有缩进的语句块和if条件无关。If语句的执行力流程看完后代码敲起来多练习几遍加深印象。下一篇用一个实例的简单版本和进阶版本来加强if条件语句的认识,更多Python基础教程可以关注我之前或者之后写的文章,几乎每天更...
if (条件1 ){ 代码1 }else if ( 条件2 ){ 代码2 }else{ 代码3 } 。 二、do..while 语句 do-while 语句是一种后测试循环语句,在对条件表达式求值之前,循环体内的代码至少会被执行一次 do { statement } while (expression); //下面是一个示例: ...
