python xlrd模块安装异常，求大侠指点急

python xlrd模块安装错误，求大侠指点急！！！
我已经装好了xlrd
import xlrd 没有错误
但是运行下面的程序就报错
import xlrd
from xlrd import open_workbook
book = xlrd.open_workbook("C:\Users\hp\Desktop\1.xls")
print "The number of worksheets is", book.nsheets
print "Worksheet name(s):", book.sheet_names()
 
Traceback (most recent call last):
  File "C:\Users\hp\Desktop\xlrd.py", line 3, in <module>
  import xlrd
  File "C:\Users\hp\Desktop\xlrd.py", line 4, in <module>
  from xlrd import open_workbook
ImportError: cannot import name open_workbook
 
奇怪的是我单独运行from xlrd import open_workbook的时候也能正常导入，求大侠指点

------解决方案--------------------
File "C:\Users\hp\Desktop\xlrd.py"
你的脚本名改一下，不要和模块同名...
