随机模块不工作.ValueError:randrange() 的空范围 (1,1, 0)

2022-01-17 00:00:00 python random numbers range

问题描述

在 Python 2.7.1 中，我导入随机模块.但是，当我调用 randint() 时，出现错误:

In Python 2.7.1, I import the random module. when I call randint() however, I get the error:

ValueError: empty range for randrange() (1,1, 0)

此错误是由 random.py 模块本身的错误引起的.我不知道如何修复它，重新安装python帮助也不知道.我无法更改版本.

This error is caused by an error in the random.py module itself. I don't know how to fix it, not does reinstalling python help. I can't change versions.

谁能给我一个工作模块的代码或告诉我该怎么做?

can someone please give me code for a working module or tell me what to do?

解决方案

你这样调用randint:

You called randint like this:

randint(1,0)

这告诉 randint 返回一个从 1 到 0 的值.从 1 到 0 的数字范围肯定是一个空范围.因此错误:

That tells randint to return a value starting as 1 and ending at 0. The range of numbers from 1 to zero is as you surely realize an empty range. Hence the error:

empty range for randrange()
