python文件名与包重名

import os
import xlrd


newpath = os.chdir('E:/')

filename = "example_copy.xlsx"

file = os.path.join(os.getcwd(),filename)

xl = xlrd.open_workbook(file)

print(xl.sheet_names())
print(xl.sheets())

 文件名是xlrd，导入包名xlrd，运行结果

D:\Python\Python36\python3.exe C:\Users\Da\PycharmProjects\untitled3\xlrd.py
Traceback (most recent call last):
  File "C:\Users\Da\PycharmProjects\untitled3\xlrd.py", line 2, in <module>
    import xlrd
  File "C:\Users\Da\PycharmProjects\untitled3\xlrd.py", line 11, in <module>
    xl = xlrd.open_workbook(file)
AttributeError: module 'xlrd' has no attribute 'open_workbook'

将文件名改成与包xlrd包不同命就可以了。

文件名与包同名，包会被文件名屏蔽，导致无法导入。python中导入单个文件和导入包是同样import
