在Python中,数字并不是一个真正的对象类型,而是一组类似类型的分类。Python不仅支持通常的数据类型(整数和浮点数。),而且能够通过常量去直接创建数字以及处理数字的表达式。 整数和浮点数 复数 固定精度的十进制数 有理分数 集合 布尔类型 无穷的整数精度 各种数字内置函数...
random.randint(1,100)随机数中是包括1和100的。python中对random.randint() 的源码解释如下 def randint(self, a, b):"Return random integer in range [a, b], including both end points."翻译过来就是返回值是在 [a, b] 区间的随机数（integer类型），其中包括 a和 b。
