如果编程语言支持运算符重载，则还应提供等号和不等号运算符的实现。

If your programming language supports operator overloading, you should also provide an implementation of the equality and inequality operators.

那个等号其实是个“赋值运算符。”

The equal sign is really called the "assignment operator."

所以这是相等操作符，然而那个单等号是一个赋值运算符。

So this is the equality operator, whereas the single equal sign is the assignment operator.

目标在于避免意外地使用单等号赋值运算符而非双等号比较运算符

The goal here is to avoid accidentally using the single-equals assignment operator instead of the double-equals comparison operator

和字符串不同的是，列表是可以修改的。方括号运算符放到一个赋值语句的等号左侧的时候，就会把对应位置的列表元素重新赋值。

Unlike strings, lists are mutable. When the bracket operator appears on the left side of an assignment, it identifies the element of the list that will be assigned.
