[英]CSV read error: new-line character seen in unquoted field
I created a python script which works with a test CSV dataset of 10 records. 我创建了一个python脚本,它与10个记录的测试CSV数据集一起使用。 When I scaled this up to the actual datasets (a few thousand rows), I am getting the following error:
当我将其扩展到实际数据集(几千行)时,我收到以下错误:
_csv.Error: new-line character seen in unquoted field - do you need to open the file in universal-newline mode?
_csv.Error:在未引用字段中看到的换行符 - 是否需要以通用换行模式打开文件?
The code is as follows: 代码如下:
with open('./Origins.csv', 'r') as csvfile:
reader = csv.DictReader(csvfile)
origincoords = ['{Y},{X}'.format(**row) for row in reader]
The full error code is: 完整的错误代码是:
Traceback (most recent call last):
File "./Driving.py", line 14, in <module>
origincoords = ['{Y},{X}'.format(**row) for row in reader]
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/csv.py", line 103, in next
self.fieldnames
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/csv.py", line 90, in fieldnames
self._fieldnames = self.reader.next()
_csv.Error: new-line character seen in unquoted field - do you need to open the file in universal-newline mode?
Perhaps there is a scale problem with the CSV reading method I am using? 也许我正在使用的CSV读取方法存在规模问题?
In a Python with universal newline support open() the mode parameter can also be "U", meaning "open for input as a text file with universal newline interpretation".
在具有通用换行符支持open()的Python中,mode参数也可以是“U”,意思是“打开输入作为具有通用换行符解释的文本文件”。 Mode "rU" is also allowed, for symmetry with "rb"
模式“rU”也是允许的,与“rb”对称
So try to change 所以试着改变
with open('./Destinations.csv', 'r') as csvfile:
to 至
with open('./Destinations.csv', 'rb') as csvfile:
If the error persists, change to 如果错误仍然存在,请更改为
with open('./Destinations.csv', 'rU') as csvfile:
