本来想用java写，奈何java太繁琐，python 功能包真丰富啊

import bluetooth

print("开始搜索附近蓝牙...")

print("找到 {} 个蓝牙设备".format(len(nearby_devices)))

for addr, name in nearby_devices:
    try:
        print("  mac地址 ：{} - 蓝牙名称：{}".format(addr, name))
    except UnicodeEncodeError:
        print(" mac地址 ：{} - 蓝牙名称：{}".format(addr, name.encode("utf-8", "replace")))

Traceback (most recent call last):
   File "",line1,in 
AttributeError: 'module' object has no attribute 'discover_devices'

原因：不能以bluetooth.py命名或者运行目录含有bluetooth.py的文件
I had the same problem, I did the mistake of naming my program file bluetooth.py , which confused python for the package resolution, you should look out for this silly mistake if this is the case .

If this is not the case then try to put your file in the directory where your bluetooth directory (in my case, C:Python27Libsite-packages) is located and then run it from there, it worked for me.
