if (condition) { // Code to execute if condition is true } 这里的“condition”是一个布尔表达式,当该表达式的值为真(通常是true或者非零值)时,if语句所包围的代码块(大括号{}中的部分)就会执行。如果条件为假,则跳过这部分代码不执行。 二、SYNTAX VARIATIONS 虽然if语句的逻辑结构在各种语言中通常保持一...

在Python中,if条件语句用于根据给定的条件执行特定的代码块。条件可以是任何返回布尔值的表达式。然而,if条件语句只能处理一个条件,无法直接计算多个"True"值。 如果你想要计算多个"True"值,你可以使用逻辑运算符来组合多个条件。常用的逻辑运算符包括"and"、"or"和"not"。
