# 使用赋值运算符赋值 a = 3 b = 5 c = a + b # 输出结果 print(c) 这段代码用于演示如何使用赋值运算符(Assignment Operator)将变量 a 和b 的值相加,并将结果赋给变量 c。最后,使用 print 函数输出变量 c 的值。 输出: 8 这是因为变量 c 的值是变量 a 和b 的和,即 3 + 5 = 8。所以输出...
The simplest assignment operator is the equal sign, which assigns the value after the equal sign to the preceding variable. As shown in Figure 1, num1 and num2 are added, and the value is assigned to the result output. Other assignment operators are much the same, the format of the arit...
eg: 特殊操作: 1.链式赋值 2.交叉赋值 3.解压赋值 3 1 2 [3, 1, 2] # _是合法的变量名,会接受值,但我们认为_代表该解压位不用接收,用_来接收表示

A single equal sign is an assignment operator, that assigns a value to a variable. Instead, we use double equal signs as the comparison operator, which compares whether 2 variables or values contain the same value. Logical Operators 逻辑运算符 and or not 三个逻辑运算符举例: number1 = 9 ...

Regular assignment statements with the = operator don’t have a return value, as you already learned. Instead, the assignment operator creates or updates variables. Because of this, the operator can’t be part of an expression. Since Python 3.8, you have access to a new operator that allows...
Python 3.8版本引入了一个新颖而实用的语法特性——海象运算符(Walrus Operator),其正式名称为“赋值表达式运算符”(Assignment Expression Operator),在Python代码中用:=表示。这个运算符让开发者能够在表达式内部进行变量赋值,从而简化代码并提高可读性。本文将深入探讨海象运算符的用法和优势,并通过实例展示如何在Python...
