python题库数学（第三版）

这次的改革主要是增加了负数，说到负数，自然要讲讲他的运算了

负数，你可简单理解为减一个数（加减法时）

就比如说-8就是减8

负数在第二位即以后是，可直接和前排符号化简（仅加减法）

负号和加法：可直接化成减号

例：8+（-9）

原式=8-9

        =-1

负号和减法：可直接化成加号

例：8-（-9）

原式=8+9

        =17

咳咳，有些跑题了，这里我就直接挂链接，点我学习

因为随机数是可以随机负数的，所以只需加上负号，即可完成今天的代码：

                    while 1:

                        if rezz == 1:
                            marshmello = int(alan+walker)
