In the following example, the “OR” operator is used along with the “if-statement” to compare two conditions. Multiple conditions are applied to the given data with the help of the “OR” operator. It will return “True” if either of the conditions is satisfied: Code: Number = 45 i...
It is possible to include anifstatement inside anotherifstatement. For example, number =5# outer if statementifnumber >=0:# inner if statementifnumber ==0:print('Number is 0')# inner else statementelse:print('Number is positive')# outer else statementelse:print('Number is negative') Run...
首先是 Go 语言,官网的FAQ专门列出了一个问题:“Why does Go not have the?:operator?”。 Go 语言不支持“?:”运算符,而是推荐使用原生的“if-else”写法。文档的解释很简短,只有一段话: Go 语言没有 ?: 运算符,因为语言的设计者们经常看到它被用来创建难以理解的复杂表达式。虽然 if-else 形式比较长,但...

可以在 if 语句块的代码中嵌套 if 语句,在其中指定另一个if语句。这是另一个假设中的一个假设, 或者我们所说的嵌套if语句. 英文: You can have nested if statements, where you specify another if statement, within your if statement block of codes. It's an if inside another if. Or what we call...

Note: As you already learned, the assignment operator doesn’t create an expression. Instead, it creates a statement that doesn’t return any value. The assignment operator allows you to assign values to variables. Strictly speaking, in Python, this operator makes variables or names refer to sp...
