The &quot; equal &quot; comparative operator must be represented by two equal signs (==) in a condition. For example, if you define a variable &quot; x &quot; with the value of 1, you can enter the condition as x==1.
在条件中， &quot; 等于 &quot; 比较运算符必须用两个等号 (==) 表示。例如，如果定义变量 &quot; x &quot; 的值为 1，则可以输入条件 x==1。
