Question

IOError：[Errno 22]无效模式（'r'）或文件名：'E：\ x07nu \ meta.csv'

f = open("E:\anu\meta.csv","r")


for line in file:

        x = line.split(",")

        print(x[0])

Answer 1

\ a正在制造问题。像\ a和\ t等字符会产生这样的问题。

改为使用原始字符串：

test_file=open(r'E:\anu\meta.csv','r')

或加倍斜杠：

test_file=open('E:\\anu\meta.csv','r')

或改为使用正斜杠：

test_file=open('E:/anu/meta.csv','r')

Answer 2

Try the following which does not interpret escape sequences of your path (like \a)

f = open(r"E:\anu\meta.csv","r")

Answer 3

如果使用Python 2.7，请以二进制模式打开'rb'。

尝试使用以下任一方法：

f = open(r'E:\anu\meta.csv','rb') as f

f = open(r'E:\\anu\\meta.csv','rb') as f
