Python_生成浮点数

我是靠谱客的博主酷炫豌豆，最近开发中收集的这篇文章主要介绍Python_生成浮点数，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

生成一定范围内的浮点数,代码如下,请指正:

def flo(start, stop, step):
    result = []
    # 计算需要的次数
    sum = int(abs((stop-start)/step+1))
    #
    for i in range(start, sum):
        result.append(start)
        start = start + step
    result.append(stop)
    return result


# call flo

b = flo(1, 3, 0.2)

运行结果为:

D:Python27python.exe C:/Users/Administrator/Desktop/PythonScripts/111.py
[1, 1.2, 1.4, 1.5999999999999999, 1.7999999999999998, 1.9999999999999998, 2.1999999999999997, 2.4, 2.6, 2.8000000000000003, 3]

Process finished with exit code 0

请各位大神指导一下,里边5个奇怪的数字怎么处理?
