ImportError:无法导入名称日志

Question

为什么会这样？

python --version=2.7.1

import urllib

def main():
    urllib.urlretrieve('http://media2.apnonline.com.au/img/media/images/2011/02/28/apple-logo_fct825x508x16_t460.jpg', 'image.jpg')

if __name__ == '__main__':
    main()

跟踪：

    main()
  File "robot.py", line 4, in main
    urllib.urlretrieve('http://media2.apnonline.com.au/img/media/images/2011/02/28/apple-logo_fct825x508x16_t460.jpg', 'image.jpg')

ImportError: cannot import name log

Answer 1

是否有可能在运行的程序所在的目录中有一个名为math.py的文件？如果是这样，python会尝试在数学模块之前导入它。

解决方案：只需将其重命名为其他内容。

提示：以后请尝试以不冲突的方式命名模块。
