为什么这个python程序不起作用? AttributeError:“模块"对象没有属性 [英] Why this python program is not working? AttributeError: 'module' object has no attribute

问题描述

我写了一个非常简单的python程序.

I wrote a very simple python program.

#!/usr/bin/env python
import random
x = random.uniform(-1, 1)
print str(x)

我从命令提示符处运行此命令.

I run this from command prompt.

python random.py

它返回错误:

Traceback (most recent call last):
  File "random.py", line 2, in <module>
    import random
  File "D:\python practise\random.py", line 3, in <module>
    x = random.uniform(-1, 1)
AttributeError: 'module' object has no attribute 'uniform'

这是一个非常简单的程序，我无法理解我在此过程中犯了什么错误.

It is a very simple program, I can't understand what mistake I did in this.

推荐答案

不要命名您的文件random.py，它是在导入自身并在其中寻找uniform.

Don't name your file random.py, it is importing itself and looking for uniform in it.

Python如何导入东西有点古怪，它首先在本地目录中查找，然后开始搜索PYTHONPATH.基本上，要小心地将您的任何.py文件命名为与标准库模块之一相同.

It's a bit of a quirk with how Python imports things, it looks in the local directory first and then starts searching the PYTHONPATH. Basically, be careful naming any of your .py files the same as one of the standard library modules.
