randint:randint是Python中的一个随机数生成函数,用于生成指定范围内的随机整数,包括指定的上下限值。 randrange:randrange也是Python中的一个随机数生成函数,用于生成指定范围内的随机整数,但不包括指定的上限值。 分类: randint属于随机数生成函数。 randrange属于随机数生成函数。 优势: randint的优势在于可以直接指定上...

xrange与range类似,只是返回的是一个“xrange object”对象,而非数组list。要生成很大的数字序列的时候,用xrange会比range性能优很多,因为不需要一上来就开辟一块很大的内存空间,这两个基本上都是在循环的时候用。 This function is very similar to range(), but returns an “xrange object” instead of a list...
