AttributeError：＆＃39; _io.TextIOWrapper＆＃39;对象没有属性＆＃39;读者＆＃39;

Question

无法在代码中出错，因为csv模块根据the documentation具有csv.reader()函数。但我仍然收到这个错误：

Traceback (most recent call last):
  File "test_csv.py", line 4, in <module>
    read = csv.reader(csv, delimiter = ',')
AttributeError: '_io.TextIOWrapper' object has no attribute 'reader'

我的代码：

import csv

with open('test_csv.csv') as csv:
    read = csv.reader(csv, delimiter = ',')
    for row in read:
        print(row)

您重新绑定了csv目标中的名称as：

with open('test_csv.csv') as csv:

这会掩盖模块名称，因此csv.reader已在文件对象上解析 。

使用其他目标：

with open('test_csv.csv') as csvfile:
    read = csv.reader(csvfile, delimiter = ',')
    for row in read:
        print(row)
