大于等于运算符(greater than or equal to,>=) 大于等于运算符用来判断一个数是否大于或等于另一个数。结果为bool,如果大于或等于返回True,否则返回False。例如1>=1为True,0>=1为False。 小于等于运算符(lesser than or equal to,<=) 小于等于运算符用来判断一个数是否小于或等于另一个数。结果为bool,如果

关系运算符，又称比较运算符。大于、小于、大于等于、小于等于、等于还有不等于。重要的还是要知道如何将它们运用在代码中。需要注意的是，双等号表示比较，单等号是赋值。Relational operator, also known as comparison operator. Greater than, less than, greater than or equal to, less than or equal to, equa...
Less than:a < b Less than or equal to:a <= b Greater than:a > b Greater than or equal to:a >= b These conditions can be used in several ways, most commonly in "if statements" and loops. An "if statement" is written by using theifkeyword. ...
<> If values of two operands are not equal, then condition becomes true. (a <> b) is true. This is similar to != operator. > If the value of left operand is greater than the value of right operand, then condition becomes true. (a > b) is not true. < If the value of left ...
