Question

我将csv文件保存在D目录中并尝试使用python编程读取该csv文件。这是我在python中的代码：

import csv

try:
     path = "D:\\abc.csv"
     with open("path", "rb") as csvfile:
         readCSV = csv.reader(csvfile, delimiter=',')
         for row in readCSV:
             print (row)    
except Exception, e:
    raise e

这是我得到的错误：

The current working directory is F:\
Traceback (most recent call last):
  File "F:\directory.py", line 16, in <module>
    raise e
IOError: [Errno 2] No such file or directory: 'path'

Answer 1

您需要删除path周围的双引号。＆＃34;路径＆＃34;是一个字符串，为了获得path变量的值，你需要按原样放置变量，以便扩展它。

with open(path, "rb") as csvfile:

Answer 2

删除路径周围的双引号。将其编辑为：

with open(path, "rb") as csvfile:

Answer 3

这一行

with open("path", "rb") as csvfile:

应该是

with open(path, "rb") as csvfile:

正如＆＃34;＆＃34;中的任何文字或者＆＃39;＆＃39;在python中将被视为字符串类型而不是变量。
