Python不能读取csv转储

Question

我想读取一个mysql csv转储但不断收到错误。我看到读了一些问题，但无法工作。

SELECT * FROM products INTO OUTFILE 'products.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n'; 

在Python

：

在MySQL

我想：

import csv 
with open('products.csv', 'r') as csvfile: 
    data = csv.reader(csvfile, delimiter=',', quotechar='"') 
    for row in data: 
     print ', '.join(row) 

，并得到：

Error: new-line character seen in unquoted field - do you need to open the file in universal-newline mode?

，并试图：

import csv 
with open('products.csv', 'rU') as csvfile: 
    data = csv.reader(csvfile, delimiter=',', quotechar='"') 
    for row in data: 
     print ', '.join(row) 

和它的工作，但它分裂包含一个换行符

，并试图细胞：

pandas.read_csv('products.csv') 

，并得到：

pandas/parser.pyx in pandas.parser.TextReader.read (pandas/parser.c:7988)()

pandas/parser.pyx in pandas.parser.TextReader._read_low_memory (pandas/parser.c:8244)()

pandas/parser.pyx in pandas.parser.TextReader._read_rows (pandas/parser.c:8970)()

pandas/parser.pyx in pandas.parser.TextReader._tokenize_rows (pandas/parser.c:8838)()

pandas/parser.pyx in pandas.parser.raise_parser_error (pandas/parser.c:22649)()

CParserError: Error tokenizing data. C error: Expected 29 fields in line 25, saw 39

我刚碰到同样的问题。我通过指定escapechar来解决它，例如：

data = csv.reader(csvfile, delimiter=',', quotechar='"', escapechar='\\')
