我正在使用pycharm并尝试使用csv库读取csv文件，但未找到阅读器模块

import csv
with open('c:/temp/scores.csv', 'r') as f:
    reader = csv.reader(f)
    for row in reader:
        print(row)

结果是：

E:\python\venv\Scripts\python.exe E:/python/csv.py
Traceback (most recent call last):
  File "E:/python/csv.py", line 1, in <module>
    import csv
  File "E:\python\csv.py", line 3, in <module>
    reader = csv.reader(f)
AttributeError: 'module' object has no attribute 'reader'
